22mm CA, 35mm FL, Mounted MgF 2 Coated Achromatic Doublet Lens

Product Details Pre-mounted in Engraved C-Mount Housings Simplify Integration into Optical Systems Less than 1.75% Reflectance per Surface @ 400 – 700nm Also Available Unmounted TECHSPEC Mounted MgF 2 Coated Achromatic Lenses feature our TECHSPEC MgF 2 Coated Achromatic Lenses pre-mounted in C-Mount housings to simplify their integration into optical systems. Designed for the visible spectrum, these lenses are coated with a single layer MgF 2 anti-reflection coating to increase light transmission. Each C-Mount housing is laser engraved with the stock number and focal length for easy identification. TECHSPEC Mounted MgF 2 Coated Achromatic Lenses are ideal for C-Mount optical systems that require on-axis spherical and chromatic aberrations to be eliminated.
