The lens is the key optical component for CO2-laser-based units. Due to its curved shape it allows to transform incident collimated beam into tiny-size area and thus concentrate the entire power of laser source in the shape of a spot.
Plano-convex lenses are the most economical transmissive focusing elements. Its prime advantage is the lower cost, whereas meniscus lenses can provide better performance, since they are specifically designed to minimize spherical aberration. The lenses of both designs can be effectively utilized for CO2-laser-based heat treating, welding, cutting, drilling and marking apparatuses.
Besides the plano-convex and meniscus lens shapes, Tydex supplies biconvex and cylindrical lenses.
Custom-made lenses are also produced.
Zinc Selenide, Gallium Arsenide and Potassium Chloride can be used for production of lenses.
Standard ZnSe and GaAs lenses are offered with both surfaces AR coating at 10.6 mm. KCl lenses are supplied uncoated.
Maximal available sizes of optical components are:
