This is a HO-BXL50-03B 50mm diameter N-BK7 double-convex lens, designed with an effective focal length (EFL) of 150mm. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor in the optical industry.
The lens is spherical in shape, featuring a base shape that is circular. It has a diameter of 50mm and a thickness at the edge of 3mm. The first radius of curvature (R1) is 155.26663, while the second radius of curvature (R2) is -155.26663. The inner and outer radii are both zero.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The wavelength for this lens is 587.6nm.
The lens is coated with BBAR (Broadband Anti-Reflection) coating, which is designed to reduce reflection and increase transmission of light over a broad range of wavelengths, specifically 400-700nm. This coating is applied to both the front and back surfaces of the lens.
