- Simplify Integration into Optical Systems
- Less than 1.75% Reflectance per Surface @ 400 - 700nm
TECHSPEC® Mounted MgF2 Coated Achromatic Lenses feature our TECHSPEC MGF2 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 MgF2 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 MgF2 Coated Achromatic Lenses are ideal for C-Mount optical systems that require on-axis spherical and chromatic aberrations to be eliminated.
