Lenses are widely used at YAG-laser apparatuses for welding, cutting, drilling, and marking as well as in based on YAG-laser other applications like collimators, magnifiers, radiometers, optical transceivers, and condensers.
Tydex offers plano-convex, plano-concave, bi-convex, bi-concave, and meniscus lenses of spherical design. Cylindrical and custom-made lenses are also available.
