Description
Znse Plane-convex focusing lens is applied to CO2 laser. One side is flat and the other side is convex. The substrate is laser-grade CVD ZnSe and coated with the double-sided anti-reflective film. The convex surface should face the perpendicular incident light beam and the plane should face the workpiece.
Znse lens is a commonly used optical glass material in the infrared band with a transmission band of 600nm-16μm. It has low absorption and thermal shock resistance, and is commonly used in thermal imaging systems, as well as in some visible optical systems, and can be used as a substrate for a variety of optical components. It is important to note that zinc selenide is a toxic material, so please wear gloves when using it and wash your hands afterwards.
