عدسات ليزر Bestform، كوارتز منصهر من الدرجة S1-UV

The fused silica is crystal clear and the bestform shape really does make a difference in spot size—I measured a tighter focus than with my old lens. The S1-UV grade handles our 355nm source without any issues.

Swapped this in for the plano-convex lens I'd been using on my CO2 setup and the difference in spot size was obvious right away. Spherical aberration is clearly well controlled with this bestform shape, and the fused silica handles the power without any thermal drift. Focus stays crisp even after an

I've been trying to get a tight laser spot for weeks, and this lens finally did it. The shape really minimizes spherical aberration, and the fused silica transmits my UV beam without any noticeable loss.
