This is a HO-BXL50-06B 50mm diameter N-BK7 double-convex lens, featuring an effective focal length (EFL) of 300mm and broadband anti-reflection (BBAR) coating for the 400-700nm wavelength range. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor in the optical industry.
The lens is a Spherical Lens of the Sub Type Spherical Lens (Convex-Convex), with a base shape of Circular. It has a diameter of 50mm, a thickness edge of 3mm, and an EFL of 300mm. The radii of curvature for the first and second surfaces are 312.109243mm and -312.109243mm, respectively. The lens is made of N-BK7 Schott glass, a popular material known for its excellent optical properties.
The lens features BBAR coating on both the front and back surfaces, specifically the HOL BBAR 0 AOI coating. This coating reduces reflection and increases transmission across the specified wavelength range, enhancing the overall performance of the lens in various applications.
