Description
Znse Meniscus focusing lens is concave and convex focusing lens. The substrate is laser grade CVD ZnSe and coated with the double-sided anti-reflective film. Meniscus focusing lens can effectively reduce spherical aberration and produce smaller light spot than plane-convex focusing lens. The convex surface should face the perpendicular incident light beam and the concave surface should face the workpiece.
These lenses are widely used by all customers producing and using industrial and medical laser systems. They are also used in laser cutting, laser welding and so on.
