Universal OD 5+ IR/Diode/Fiber Laser Engraver Enclosure – 1064nm blocking window

Universal OD 5+ IR / Diode / Fiber Laser Engraver Enclosure – 1064 nm blocking window

The day the IR module arrives, your diode goggles and your amber enclosure lid stop protecting you. A 1064 nm beam is invisible: the blink reflex that laser exposure limits assume for visible light never fires, and the eye focuses the beam onto the retina exactly as it would a green dot. Diode goggles are a blue filter. So is the amber acrylic on a diode enclosure — it passes most near-infrared straight through. And the module exists to mark metal, which is a mirror at this wavelength: gold reflects roughly 97% of a 1064 nm beam, polished aluminum around 90%, stainless around 65%. Every job throws stray reflections off the workpiece in directions you aren't looking, and a reflected beam can stay above the ocular exposure limit across any room in your house. The 2 W on the box is an average; the module marks metal with short pulses whose peak power is measured in kilowatts. Everyone with line of sight to the work is exposed, not only the operator.

The Universal IR / Diode / Fiber Laser Engraver Enclosure by Clearview Plastics is an enclosure built for the wavelength you can't see. It is the 400 mm Universal V3 frame with opaque black ¼″ aluminum composite panels on every side, so a stray reflection ends at the panel instead of continuing into the room. It sets over the machine and holds it in a contained working envelope — no fabrication, no drilling, no modification — and it takes an optional 6 × 12″ dual-wavelength viewing window rated for the blue diode head and the 1064 nm IR module at once. One enclosure, both heads.

What's on it

• Opaque aluminum composite walls — a reflection off the workpiece stops at the panel instead of continuing into the room.
• 6 × 12″ dual-wavelength window, optional — laser-safety acrylic rated by its manufacturer at OD 5+ across 190–533 nm and OD 6+ at 1064 nm, so you can watch either head run. Leave it off for a fully opaque build.
• Hood camera mount — frame the job in LightBurn and watch it from the screen, which is how you monitor the opaque build.
• Three grommet ports — air-assist tubing and cables pass through without leaving a gap for smoke or light.
• Slide vents and intake strips — give the exhaust makeup air to pull. Closed vents choke the airflow.
• Magnetic front door and hinged lid — load parts from the front, reach the gantry from the top, without tools and without lifting the enclosure off.
• Two 4″ exhaust positions — mount the fan or the duct adapter on whichever side faces your window or your filter.

Three selections build the kit

The enclosure comes with the black aluminum composite panels. The viewing window and the printed parts are selections on top of it, and accessories are added after that. Opaque means opaque: the standard build has no window. If you want to watch the job through the lid, add the window; otherwise plan on the hood camera — there is no line of sight into the chamber, which is the point.

• The enclosure — black ¼″ aluminum composite panels, the 2020 aluminum extrusion frame, rust-resistant hardware, and the files for every printed part.
• Viewing window — none (fully opaque, monitored by camera), or the 6 × 12″ dual-wavelength window set into the lid. The window stock is Laser Safety Industries Double-YAG acrylic, 0.140″, with 26% visible light transmission.
• Printed parts — print the brackets yourself from the included files, or add the pre-printed parts kit and build straight out of the box.

Optional accessories

Pre-printed parts kit, LightBurn-compatible hood camera, dual-channel USB LED lighting kit, 95 CFM exhaust fan with mounting bracket, 200 CFM compact fan, window exhaust kit (inline fan, window insert, and 16 feet of hose), and Print Pro 3 by Donaldson filtration. You supply a 4″ hose and clamp.

Air management

The enclosure contains what comes off the part. The duct or the filter does the rest. Marking metal and dark plastic puts soot and fine particulate into the air at bench height, most of it too small to see; contained in the chamber it can be carried out of the room or absorbed by a filter, and loose in the room it can't be.

Setup is three steps: pick the exhaust side (two 4″ port positions — mount the fan or the duct adapter on the side that faces your window or your filter), open the slide vents and intake strips so the exhaust has makeup air to pull, and run a 4″ hose with a clamp out a window or to a filter. Then choose a path. Ducting out a window with the window exhaust kit carries the fume out of the room instead of treating it in the room, and it needs a window. Running to a Print Pro 3 by Donaldson suits a room you can't vent, an office, or a shared space; it is built for the fume and particulate laser marking produces. A 95 or 200 CFM fan on the port replaces the chamber air every few seconds instead of letting it sit.

Fit and support

Sized for the 400 mm gantry class, on the same frame as our diode Universal V3. If your machine's frame fits inside 740 × 745 mm, it fits. If you already run our Universal V3 with acrylic panels, the frame and the printed parts are the same — only the panels change.

CNC-routed in California. Built in the USA: every enclosure is cut, fabricated, and assembled in our own shop in California. One year warranty against manufacturer defects. Standard kits ship in 10 business days or less; assembled kits in 15. Assembles with a Phillips screwdriver and a 2.5 mm hex wrench — plan on 1–2 hours. Every printed part is in the file repository you get after ordering; if one breaks or gets revised, print a new one.

Which machines this is for

Open-gantry (CNC-style) engravers in the 400 × 400 mm class that run a 1064 nm infrared head — either a bolt-on IR module on a diode machine, a dual-laser machine, or a native 20 W fiber gantry. These are not galvo markers; for desktop fiber, MOPA, and UV galvo markers see our galvo laser marker enclosures.

Why 1064 nm needs a different enclosure

The eye's cornea and lens are transparent from about 400 to 1400 nm, so a 1064 nm beam reaches the retina and is focused there like any visible light — the eye's own optics concentrate the irradiance by roughly a hundred-thousand-fold. What is missing is the warning. There is no flash, no glare, no pupil response, so the aversion reflex that the visible-light exposure limits assume within a quarter of a second never happens; the standards assume a ten-second exposure for near-infrared for exactly that reason. Retinal injury from 1064 nm is thermal and painless, and depending on where it lands it may not be noticed until an eye exam.

The second problem is the workpiece. Metals are highly reflective at 1064 nm, and a specular reflection off a polished tumbler, a brass coin, or a ring mandrel keeps most of the beam's power and collimation. That is why an IR job needs the beam path enclosed, not just the operator wearing eyewear. The third problem is the material of the enclosure itself. Clear and amber acrylic transmit most near-infrared; the dye systems that make a diode panel amber are tuned to the 400–520 nm band and do nothing five hundred nanometers further out. Our own spectrometer report on the amber panel we sell for diode enclosures shows OD 3+ through 530 nm and roughly 89% transmission from 560 nm to the end of the scan at 800 nm. Aluminum composite has no transmission spectrum to argue about: it is opaque at 450 nm, at 1064 nm, and at every wavelength in between. A reflected beam ends at the panel, not in the room.

The window: one rating for both heads

Most owners run both heads, and no amber diode window is rated at 1064 nm. The optional lid window is cut from a laser-safety acrylic rated by its manufacturer, Laser Safety Industries, at OD 5+ across 190–533 nm (which covers 445–455 nm blue diodes), OD 5+ across 880–1100 nm, and OD 6+ at 1064 nm, with 26% visible light transmission. The same lid works for the 20 W diode on Tuesday and the IR module on Wednesday. Twenty-six percent is dim enough to tame the glare and bright enough to watch a tumbler turn on the rotary. If you'd rather have no line of sight at all, skip the window and use the hood camera; the enclosure is opaque everywhere else either way.

Manufacturer's spectral data for the window stock, 400–1200 nm. The curve sits above OD 7 across the blue diode band and across 910–1070 nm; the pass-band near 590 nm is what you see through. Published ratings: OD 5+ at 190–533 nm, OD 4+ at 850–879 nm, OD 5+ at 880–1100 nm, OD 6+ at 1064 nm, OD 5+ at 10,000–11,000 nm. The rating is the manufacturer's rating for the window material; the aluminum composite panels carry no rating.

The fume from marking metal and plastic

An IR head is mostly used on metal and dark plastic, and the fume is different from the wood smoke a diode makes. Laser-generated particulate is overwhelmingly sub-micron — roughly nine-tenths of it by weight is under one micron, which is small enough to reach deep into the lungs and far too small for a shop vac or a room fan to do anything about. Marking stainless steel vaporizes chromium and nickel, and chromium and nickel compounds are treated as carcinogens by occupational health regulators. Marking plastics adds volatile organic compounds; a NIOSH evaluation of laser marking found the highest VOC concentrations on plastic substrates. Contained in a 0.22 m³ chamber, that fume can be carried out a window or absorbed by a filter; a 95 CFM fan turns the chamber air over about every five seconds, a 200 CFM fan about every two.

What you'll mark under this hood

Jewelry — rings, pendants, bracelets in gold, silver, and platinum, with a ring mandrel or rotary. Stainless tumblers, dog tags, pet tags, and keychains. Challenge coins in brass and copper. Anodized aluminum business cards, plates, and phone cases. Knives, tools, and firearm accessories, including rust removal. Dark and opaque plastics — black ABS, PC, keycaps, and black PLA prints, which IR marks white. PCB and circuit boards. Slate, stone, ceramic tile, and brick. Glass and ceramic with marking paper or spray. Leather without burn marks. Business nameplates, serial plates, and asset tags. Watch parts. The enclosure's internal height, about 400 mm, clears the rotary and the head with room for an 80 mm tumbler.

Running a Class 4 laser as a business

Every 1064 nm module on the list above is a Class 4 laser. If you sell what you mark, an enclosure that contains the beam path and the fume is the engineering control a laser safety program starts with, and it is what a landlord, an insurer, or a shared-workshop manager will ask about first. It sits alongside OD-rated eyewear for everyone in the room and the machine's own interlocks; it does not replace either.

On laser class

This enclosure contains the beam path, the glare, and the fume. It does not change your laser's class, it is not certified to ANSI Z136.1, and it is not a certified protective housing. The window rating is the manufacturer's rating for the window stock; the aluminum composite panels carry no rating — opaque is a property of the material, not a certification. Everyone in the room wears OD-rated eyewear for the wavelength in use whenever the laser runs, and the machine's own interlocks stay in place. If your workplace requires a certified Class 1 solution, tell us before you specify this product and we will tell you honestly whether we can meet the requirement.

About Clearview Plastics

Neil Henderson here, owner and head designer at Clearview Plastics. We build every enclosure in-house in California. Our panels are CNC-routed for accuracy, with parts designed for each machine we support — this isn't a generic box off a marketplace. When you order through us, you work directly with me, and that relationship comes with my genuine appreciation and hands-on support.

Frequently asked questions

Do my diode laser goggles work with the IR module?
No. Diode goggles are rated for blue (about 450 nm). A 1064 nm module needs eyewear rated for 1064 nm — xTool's own FAQ specifies OD 5+ at 1064 nm for every operator and observer. The enclosure contains the beam path; it does not replace the eyewear.

Does the amber lid on my diode enclosure stop the IR beam?
No. Amber acrylic is a blue filter. Our own spectrometer test of the amber diode panel shows it passing about 89% of the light from 560 nm through 800 nm, and acrylic stays transparent through the near-infrared. That is why this enclosure uses opaque aluminum composite, and why the optional window is a dual-wavelength laser-safety stock rather than amber.

Why is there no window on the standard build?
Because opaque is the point. With no line of sight into the chamber there is nothing for a reflection to come through, and the hood camera shows you the job in LightBurn. If you want to watch through the lid, add the 6 × 12″ dual-wavelength window.

Can I run both the diode head and the IR module in this enclosure?
Yes. The panels are opaque at both wavelengths, and the optional window is rated OD 5+ for blue diode and OD 6+ at 1064 nm, so you swap heads without swapping enclosures.

Do the panels absorb the laser?
They stop it. Aluminum composite is opaque, so a reflection off the workpiece ends at the enclosure wall rather than passing into the room; some of that energy scatters inside the chamber at a fraction of its original intensity and some warms the panel, and none of it transmits. That is a description of the material, not a certification. The panels carry no protection rating, the enclosure does not change your laser's class, and it does not replace OD-rated eyewear.

Will my machine fit?
The working envelope inside the frame is about 740 × 745 mm with 400 mm of height. Every machine in the compatibility list above fits. If yours isn't listed, send us the model and the frame dimensions and we confirm the fit before you order.

I already own a Clearview Universal V3 with acrylic panels. Do I need a new enclosure?
No. The frame, hardware, and printed parts are the same. Contact us about swapping to the aluminum composite panel set.

Does marking metal make fumes?
Yes. Marking vaporizes a thin layer of the surface into sub-micron particulate — on stainless that includes chromium and nickel compounds — and marking plastic adds volatile organic compounds. The enclosure contains it; a 4″ hose carries it out a window, or a Print Pro 3 by Donaldson filter absorbs it for a room you can't vent.

Is it safe to run with kids or pets in the room?
Everyone with line of sight to a running Class 4 laser is an observer, and observers need the same OD-rated eyewear as the operator. An opaque enclosure with the doors closed removes the line of sight; it does not change the laser's class, so treat the room as a laser area whenever the machine runs.

Does this enclosure make my laser Class 1?
No. It contains the beam path, the glare, and the fume, but it is not certified to ANSI Z136.1 and does not reclassify a Class 4 laser. If your workplace requires a certified Class 1 solution, tell us before you specify this product and we will tell you honestly whether we can meet the requirement.

What's included, and what do I supply?
The base kit includes the aluminum composite panels, the extrusion frame, and hardware; you print the brackets from the included files, or add the pre-printed parts kit. You supply a 4″ hose and clamp, and for regular use we recommend adding a fan or filter.

Do you ship internationally?
Yes. Shipping is calculated at checkout via USPS, UPS, or FedEx (HS code 8538.10). Express services often cover import fees, but additional VAT, tariffs, or fees may apply depending on your country.

What is your return policy?
30 days. Unused, undamaged panels with the masking fully attached are eligible for a full refund less return shipping. If panels are damaged after shipment or the protective mask has been removed, we can't offer a refund. To check fitment, consider partially assembling with the mask still on.
