ZnSe-px-38.1-50 38.1 mm Dia. CVD ZnSe Plano-Convex Lens; EFL=50.8mm Uncoated

This is a 38.1 mm diameter Plano-Convex lens made of CVD ZnSe (Zinc Selenide) material, sourced from Alkor Technologies. The lens is uncoated and features a planar surface on one side and a convex surface on the other, with a 71.46 mm radius of curvature (RoC). The lens has a thickness of 2 mm at the edge and 4.6 mm at the center, making it suitable for applications requiring high precision and minimal distortion.

The lens has an effective focal length (EFL) of 50.8 mm, which is the distance from the lens's center to the focal point when the lens is placed in an optical system. This EFL makes the lens suitable for use in various applications, including laser beam shaping, beam expansion, and imaging systems.

The lens is made of ZnSe material, which has excellent transmission properties in the infrared region, making it ideal for applications in the 10.6 µm wavelength range. The material also has a high refractive index and a low dispersion, which helps to minimize chromatic aberration in optical systems.

The item data does not provide information about the coating of the lens. Therefore, it is assumed to be uncoated. However, coated versions of this lens are also available from Alkor Technologies, which can provide additional benefits such as improved transmission, reduced reflection, and better environmental resistance.
