Category: Best Form Lenses

When focusing a laser beam to a minimum spot, the shape of a single element lens that most effectively reduces spherical aberration is called bestform. The front and back radii of these optical lenses are chosen to be of a specific ratio; determined by the proper shape factor, which is governed by the lens material.

At Esco, we manufacture Bestform lenses from the highest quality optical grade materials. Only materials with superior homogeneity specifications are used in laser applications. Our pitch polishing department provides optic lenses with excellent surface quality, a characteristic that is necessary for limiting scatter and bringing our customers optimal results.

Bestform Laser Quality Lenses are made from S1-UV Grade Fused Silica.

For custom design lenses, please contact our sales staff and we will be glad to help you.

Olivia R. ★★★★★

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.

Sofia ★★★★★

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

Grace ★★★★★

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.
