HO-BXL12.5-02B 12.5mm Dia. N-BK7 Double-Convex Lens; EFL=25mm BBAR 400-700nm
This is a high-quality double-convex lens from Holmarc Opto-Mechatronics, designed for use in a wide range of optical applications. The lens has a diameter of 12.5mm and a thickness at the edge of 2mm, making it compact and versatile. The effective focal length (EFL) of this lens is 25mm, providing a moderate level of magnification.
The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum. The lens is coated with BBAR (Broadband Anti-Reflection) coating, which enhances its light transmission capabilities, particularly in the 400-700nm range. This coating reduces surface reflections, improving the overall efficiency and performance of the lens.
The lens features a spherical shape, with radii of curvature of 25.455917mm for the first surface and -25.455917mm for the second surface. This shape is commonly used in optical systems due to its simplicity and effectiveness. The lens does not have any inner or outer radius, indicating a uniform thickness.
