UV Laser Marker Engraver Enclosure with Laser filtering OD3+ Acrylic (Universal Fit)

The UV Laser Marker Engraver Enclosure with OD3+ Laser-Filtering Acrylic by Clearview Plastics is a made-to-fit safety and ventilation enclosure for 355 nm UV galvo laser markers — machines like the ComMarker Omni 1. Its fully transparent OD3+ laser-filtering acrylic panels give you a clear view of your work from the front, back, sides, and top, while blocking 99.9%+ of stray UV light and containing the fumes.

This is a "set-over" enclosure that drops over your UV marker and controller, offered in multiple sizes so you can match your machine — or size up to the media you're marking. It assembles in about 20–30 minutes with a screwdriver and hex wrench, and can be configured with the doors, sealing, interlock, and filtration a professional shop needs (see "Configure your enclosure" below).

Built for UV galvo laser markers

This enclosure is made to fit the popular desktop 355 nm UV markers, including:

• ComMarker Omni 1
• Aeon Laser ST5 / ST10 / ST15J
• Boss Laser UV markers
• Cloudray UV-5
• Haotian UV markers
• Keyence UV marking heads (MD-U series and similar)
• Longer Nano Pro
• Most desktop 355 nm UV galvo markers with a controller

Full visibility with real UV light-filtering

UV "cold" lasers mark without burning, but 355 nm is still a Class 4 hazard to eyes and skin, and the photochemical process gives off ozone and fine fume. This enclosure keeps the view open while cutting the danger:

• OD3+ laser-filtering acrylic — spectrometer-tested to block 99.9%+ (1000×+ reduction) of 355 nm laser light, so stray beams are dramatically attenuated.
• Fully transparent panels on all sides — front, back, sides, and top, for the best possible workpiece visibility.
• Door gasketing — seals the door perimeter to keep fumes and ozone in and block light leakage around the edges.

Note: the OD3+ panels dramatically reduce stray-light exposure and are spectrometer tested. However they do not reclassify your Class 4 laser. Always wear OD-rated UV safety glasses while the laser is in use. If you need a higher-rated window (OD6+) or a formally certified build, see our heavy-duty UV / Fiber Galvo enclosure or contact us.

Contain the fumes and ozone

• 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 — choose the size that matches your machine and media.
• 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, ozone, 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.

About Clearview Plastics

Neil Henderson here, owner and head designer at Clearview Plastics. My shop is a California-based artisan design studio, and we build every enclosure in-house in Sacramento. Our panels are professionally CNC-cut for accuracy, with parts designed specifically 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 skilled, personal help.

Frequently asked questions

What does an OD3+ rating mean?
OD3+ means that if a laser beam hits the panel, less than 0.1% (one-thousandth) of the original power can get through — usually much less, since our panels are spectrometer-tested above OD3 across the relevant wavelengths. It reduces stray-beam intensity by 1,000× or more, making the panels safe for incidental viewing during normal operation. It is not a certified laser-viewing window and does not reclassify your laser.

Should I get this or the OD6+ heavy-duty enclosure?
This OD3+ acrylic enclosure gives you the clearest all-around visibility and is ideal for UV markers like the ComMarker Omni 1. If you want a higher-rated OD6+ UV window with aluminum-composite panels for a more industrial build, choose our UV / Fiber Galvo Laser Marker Enclosure instead.

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 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.
