Overview

The 1.5-inch (38.1 mm) lens assembly is Universal Laser Systems’ go-to optic for ultra-fine engraving, micro-text, and photo-quality etching. By positioning the focal point closer to the work surface and producing a spot size roughly 40 % smaller than a 2.0″ lens, it captures the highest possible resolution from your CO₂ laser—while also granting an extra ½″ (12.7 mm) of Z-axis clearance for taller parts.

Average focal length: 1.5″ (38.1 mm)
Focus tolerance: ±0.075″ (±1.905 mm)
Typical spot diameter: ≈0.003″ (0.076 mm)

Key benefits

Advantage What it means for you
Pin-sharp detail Engrave fonts under 1 mm, intricate logos, and high-resolution photos with crisp edges.
Field-upgradeable Drops into any supported PLS or VLS system (1996 +); swap lenses in minutes without tools.
Extra table height Shorter focal length adds ½″ (12.7 mm) of Z travel—handy for thicker jigs or fixtures.
Interchangeable Keep multiple lenses on hand; change optics to match the job without realignment headaches.
Thin kerf on fine cuts Produces narrow slots and minimal char on thin materials and veneers.


Limitations to keep in mind

Constraint Impact
Closer to the work Lens sits nearer the material—protect it from resin, smoke, and debris.
Limited thick-cut capacity Best for materials ≤ 0.20″ / 5 mm; beam divergence reduces power density at depth.
Tight focus window ±0.075″ tolerance means material must be flat and firmly fixtured.
Model exclusions Not compatible with PLS 6MW, ILS, or XLS platforms.


Ideal applications

  • Photo engraving on hardwood, anodized aluminum, or coated metals

  • Micro-text security marks

  • Fine-detail acrylic or veneer inlays

  • Kiss-cut labels and thin-film stencils

  • Delicate paper or cardstock work where edge char must be minimal
