HO-BXL25-06B 25mm Dia. N-BK7 Double-Convex Lens; EFL=150mm 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 25mm and a thickness at the edge of 2mm, making it compact and robust. The effective focal length (EFL) of this lens is 150mm, 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 across the 400-700nm wavelength range. This coating reduces unwanted reflections and increases the overall efficiency of the optical system.
The curvature of the lens is defined by its first and second radii of curvature, which are 155.968303mm and -155.968303mm respectively. This spherical shape ensures a wide field of view and low distortion. The lens is unmounted, providing flexibility for integration into various optical systems.
