ComMarker B6 MOPA Fiber Laser Enclosure with OD7+ Laser Viewing Window

The ComMarker B6 MOPA Enclosure by Clearview Plastics is a heavy-duty, industrial-grade safety and ventilation enclosure sized for the ComMarker B6 JPT MOPA fiber laser marker. The B6 is one of the most popular MOPA markers in any US workshop — and it ships as a completely open machine. That means the 1064 nm beam, the reflected glare off the very metal you're marking, and the metal fume all end up in the room with you.

This enclosure closes that gap. 1/4" aluminum composite panels stop the beam, an OD7+ laser-safety viewing window lets you watch the job run, and a 4" exhaust port pulls the fume out. It sets over the B6 and its power brick, assembles in about 20–30 minutes, and can be configured with the doors, sealing, interlock, and filtration a working shop actually needs.

Built for the ComMarker B6 MOPA

This enclosure is designed and sized around the following configurations:

• ComMarker B6 MOPA — 20W, 30W, and 60W JPT M7 configurations
• ComMarker B6 standard (non-MOPA) fiber — same chassis
• Machine footprint approx. 16.9" W × 9.6" D × 21.7" H (430 × 245 × 550 mm) with the Z column standing
• 110 × 110 mm, 150 × 150 mm, 200 × 200 mm, and 300 × 300 mm lens configurations

All four sizes are selectable in the configurator above: Medium 15.75 × 23.75 × 27.5" · Large 18 × 29.5 × 30.5" · XL 21.5 × 29.5 × 34" · XL+ 21.5 × 31 × 38.25" (W × D × H). Not sure? Send us your machine and the media you mark and we'll point you to the right size.

Real laser-light containment — the OD7+ window

Unlike a hobby box, this enclosure is built for genuine beam containment. MOPA and fiber galvo markers are Class 4 lasers: 1064 nm is an invisible infrared beam that reflects off the very metal you're marking, straight back into the room.

• OD7+ viewing window (1064 nm) — an 11 × 11" laser-safety window (800–1100 nm, ~30% transmittance) so you can watch a fiber / MOPA job without the infrared reaching your eyes.
• Aluminum composite panels — opaque, rigid, and beam-stopping; not clear acrylic.
• Door gasketing — seals the door perimeter to keep fumes in and block stray light leakage around the edges.

Contain the fumes and soot

• 4" exhaust adapter — connects a flexible 4" hose on the rear panel to vent outdoors or to a filter.
• Fan & venting options — add a 95 CFM or 200 CFM fan, or our window exhaust kit, for the extraction your workload needs.
• Donaldson AD350 filter — step up to a heavier-duty Donaldson AD350 filtration unit purpose-built for laser marking when venting outside isn't an option.
• Flow-control vents — slide-open vents on the front and sides tune airflow for better extraction.

Configure your enclosure

Build the enclosure to your shop with the options in the product configurator above:

• Size — Medium, Large, XL, or XL+ (see the size guide above and Specifications below).
• HD hardware upgrade — metal hinges, heavier binding-screw hardware, and metal door pulls.
• LightBurn hood camera — hood-mounted USB camera for accurate part alignment and LightBurn tracing.
• Additional side doors — add side-door access; with two side doors the enclosure doubles as a pass-through for oversized or long media.
• Additional seam sealing — extra sealing for tighter fume and light containment.
• Magnetic door interlock switch — a 2-wire interlock lead to tie into your machine's safety circuit.
• Delivered assembled — have it shipped built and ready to use instead of flat-packed.

Frequently asked questions

Which window do I need for the ComMarker B6 MOPA?
The OD7+ window — it's rated for the 1064 nm infrared a fiber or MOPA source puts out. If you also run a 355 nm UV marker, we make an OD6+ UV window; tell us and we'll set it up.

Does this reclassify my Class 4 laser to Class 1?
No. This enclosure contains the beam, glare, and fumes and dramatically reduces stray-light exposure, but it is not certified to reclassify your laser or to meet ANSI standards. Always wear OD-rated safety glasses for your wavelength and follow Class 4 protocols. If you need a formally certified Class 1 solution, contact us about our Worksafe enclosure.

What are the exhaust and filtration options?
A 4" exhaust adapter is included to vent outside via a flexible hose. Add a 95 CFM or 200 CFM fan or our window exhaust kit, or step up to a heavy-duty Donaldson AD350 laser-rated filtration unit for indoor operation.

Can it act as a pass-through for long or oversized media?
Yes. Add the optional side doors — with two side doors, the enclosure opens on both sides so you can pass long or large stock straight through.

Can I get it assembled?
Yes. Choose the delivered-assembled option and it ships built and ready to use instead of flat-packed. You can also add a magnetic door interlock (2-wire lead) and extra seam sealing.

What if my machine doesn't measure the way you've listed it?
Send us your actual base width, depth, and standing height with the column at your normal working focus. We'll confirm the size before you order, and if nothing standard fits, we cut custom.

What is your return policy?
We offer a 30-day return policy. 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.
