HO-BXL12.5-02C 12.5mm Dia. N-BK7 Double-Convex Lens; EFL=25mm Single Layer MgF2
The HO-BXL12.5-02C is a high-quality double-convex lens offered by Holmarc Opto-Mechatronics. This lens, with a diameter of 12.5mm, is designed for use in a wide range of optical applications. The lens features an effective focal length (EFL) of 25mm, making it suitable for systems that require a moderate level of magnification or reduction.
The lens is crafted from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, ensures high transmission and low dispersion, making it an ideal choice for many applications. The lens geometry includes a thickness of 2mm at the edge, with the front and back surfaces featuring radii of curvature of 25.455917mm and -25.455917mm, respectively.
The HO-BXL12.5-02C is coated with a single layer of Magnesium Fluoride (MgF2), which is applied to both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly in the visible spectrum. The coating is specified as "hol mgf2 0 aoi," indicating a broadband anti-reflection coating with a zero-degree angle of incidence.
