Bestform Laser Quality 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. We believe that only materials with superior homogeneity specifications should be 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 either S1-UV Grade Fused Silica or BK7 Optical Glass. For custom design lenses, please contact our sales staff and we will be glad to help you.
