Overview
The 20W UV Laser is the top power tier in our UV catalog, built around the JPT Seal-355-20S source. At 20 watts average power with M² less than 1.2 beam quality and 355 nm wavelength, this is the right machine for high-volume industrial UV marking on glass, plastic, ceramic, PCB, and polymer films. The 20W steps up from the 15W’s chassis to a larger 400 × 205 × 124 mm source housing at 15 kg, which accommodates the heavier optics and higher power consumption that 20W demands.
Production buyers reach the 20W UV tier when the 15W is hitting throughput limits on multi-shift production lines, or when the work itself moves to materials and mark depths that need more power (deeper engraving on glass, faster cycle times on dense data matrix codes, larger workpiece coverage at production speed). The 20W operates at the same 40 to 300 kHz frequency range and same pulse architecture as 10W and 15W, so software workflow is consistent across the Seal-355 series.
What you get from JPT Laser Shop: a verified JPT Seal-355-20S source with traceable serial, the integrated 1000W water chiller, the Sino-Galvo SG7110 scanning head, DDP shipping with customs and duties paid for US, Canada, and EU buyers, plus an 18-month warranty on UV source and machine. We are an authorized JPT distributor; the Seal-355-20S is verified against JPT’s published datasheet on en.jptoe.com per shipment.

Practical guidance: 20W UV is the right tier when 15W cycle times are the production bottleneck on multi-shift work, or when the workload involves larger workpieces, deeper marks, or denser data matrix codes. The 20W’s slightly relaxed pulse-to-pulse stability (RMS less than 5% versus 3% on 10W and 15W) is the only spec compromise; for typical industrial marking this is not visible in output quality.

Software and upgrade options
This UV machine ships with the standard Sino-Galvo SG7110 galvo head and EZCad 2 software included on USB. Unlike the fiber catalog, the UV catalog does not offer an intermediate 2.5D upgrade; UV applications either work on flat surfaces (the standard head is sufficient) or require full 3D dynamic focus (Feeltek upgrade below).
Base configuration: SG7110 head + EZCad 2 + LightBurn via adapter
The standard configuration handles all flat-surface UV marking. EZCad 2 is the UV control software and has dot-matrix raster and photo-engraving modes well suited to UV-sensitive materials. LightBurn is supported via a USB adapter for operators who prefer that workflow.
3D upgrade: Feeltek FR10-U dynamic-focus head + LenMark (USD 5,500)
The FR10-U steers focus in software (LenMark) and uses no swappable field lens — up to a 600 × 600 mm field.
This upgrade replaces the standard SG7110 with the Feeltek FR10-U 3D dynamic-focus head. This is the UV-specific Feeltek model with optical coatings and beam-path tuning for the 355 nm wavelength. The upgrade adds LenMark software (Feeltek’s controller-side 3D mapping software). What you gain: continuous focal-length adjustment as the galvo mirrors point the UV beam across a curved or three-dimensional workpiece. UV is the right wavelength for marking glass, ceramic, clear plastics, silicone, and coated metals; the 3D head extends that capability to round, domed, or contoured versions of those workpieces.
When to choose the 3D upgrade: production volume on curved workpieces in UV-suited materials. Perfume bottles, cosmetic packaging, wine bottle accents, watch case-backs in ceramic, pharmaceutical vials, glassware for hospitality and luxury brands. If you are running batches of dozens to thousands of curved UV-suitable parts per shift, the 3D head dramatically cuts cycle time versus repositioning the workpiece between focal heights. For one-off curved jobs the standard fixed-focus head still works but is much slower per piece.
Our 3D UV engraving guide walks through the complete workflow from CAD model to engraved curved part using the Feeltek and LenMark pipeline.
Marking area by lens
The included lens choice determines the marking area on the workpiece. Every JPT UV machine ships with two lenses of your choice from the standard set; the 175 mm lens is included by default unless you specify otherwise at checkout.
| Lens focal length | Marking area | Best for |
|---|---|---|
| 70 mm | 70 x 70 mm | Small parts: micro-text on electronics, fine-detail glass marking |
| 110 mm | 110 x 110 mm | Medium UV work: small bottles, PCB boards, electronic enclosures |
| 175 mm (default) | 175 x 175 mm | General UV production: cosmetic packaging, mid-size glass and plastic parts |
| 210 mm | 210 x 210 mm | Larger UV parts: wine bottle accents, larger ceramic panels |
| 300 mm | 300 x 300 mm | Maximum area: full-field UV marking on large flat parts |
Configuration and capability summary
| Configuration | Head | Software | Use case |
|---|---|---|---|
| Base (standard) | Sino-Galvo SG7110 | EZCad 2 (USB), LightBurn (via adapter) | Flat UV marking on glass, ceramic, plastics, coated metals |
| 3D upgrade (USD 5,500) | Feeltek FR10-U | LenMark (Feeltek) | Curved or 3D UV workpieces in production volume |
The 3D upgrade is installed at the factory at the time of order. Adding it later requires shipping the head back as a service exchange. If you know at purchase that your UV work will include curved workpieces in production volume, configure the upgrade at checkout.

Frequently asked questions
Is 20W UV worth the step up from 15W?
Yes when production throughput is the bottleneck. The 20W delivers 33% more power than 15W at the same chiller and software profile, which translates to roughly 20-25% faster cycle times on production work. The trade-off is the 15 kg source versus 9.8 kg, a larger chassis footprint, and slightly relaxed pulse-to-pulse stability (RMS less than 5% versus 3%). For most industrial buyers running multi-shift production, the throughput gain justifies the trade-offs.
Why is pulse-to-pulse stability slightly worse at 20W?
JPT specifies the Seal-355-20S at RMS less than 5% pulse-to-pulse, versus less than 3% on the 10W and 15W tiers. This is a normal consequence of higher power UV physics; the additional power requires slightly larger active medium, which trades back some pulse stability. For typical industrial marking the difference is not visible in output; for very critical work where exact pulse energy matters batch-to-batch, the 15W tier is the more consistent choice.
What is the realistic throughput on industrial PCB lines?
500 to 1200 boards per hour for typical PCB serialization mark sizes. The throughput depends heavily on the mark complexity (single serial number versus dense 2D data matrix) and the line feed integration.
Does 20W UV cut through thin glass?
Not in production. UV at 20W can do shallow drilling on glass and surface marking, but glass through-cutting is not a UV laser application. For glass cutting, dedicated glass cutting lasers or mechanical scoring are the right tools.
Delivery and customs?
5 to 7 weeks total. DDP includes customs duties for US, Canada, EU 27. Outside DDP zones, free shipping but customs is the buyer’s responsibility.
Is this a genuine JPT source?
Yes, JPT Seal-355-20S verifiable against JPT’s published datasheet on en.jptoe.com.
