Industrial Laser Quality Lenses

Esco manufactures special plano-convex lenses to act as replacement elements for industrial Nd: YAG lasers that operate at 1.06 µm. These lenses are guaranteed to meet or exceed the performance requirements of your original laser equipment, derive from Schlieren-free fused silica, and multilayer AR-coated to resist thermal damage.

Custom industrial laser lenses are also available and nearly any focal length is possible. Contact us for more information regarding the various custom applications Esco can manufacture for you.
