HO-BXL25-1.6B 25mm Dia. N-BK7 Double-Convex Lens; EFL=40mm BBAR 400-700nm
This is a HO-BXL25-1.6B 25mm diameter N-BK7 double-convex lens, designed with an effective focal length (EFL) of 40mm. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor in the optical industry. The lens features a BBAR coating suitable for the wavelength range of 400-700nm, ensuring high transmission and minimal reflection.
The lens is spherical in shape, with a base shape of a circle. The first radius of curvature (R1) is 40.685818, while the second radius of curvature (R2) is -40.685818. The lens has a thickness of 2mm at the edge. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens.
The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The material is Schott branded, ensuring high quality and reliability. The lens is designed to work at a wavelength of 587.6nm, making it suitable for a wide range of applications.
The lens is coated with a BBAR coating on both the front and back surfaces. This coating reduces reflection and increases transmission, making it ideal for applications where high light transmission is required. The coating is specified as "hol bbbar 0 aoi", indicating a broadband anti-reflection coating with a 0-degree angle of incidence.
