HO-BXL25-20B 25mm Dia. N-BK7 Double-Convex Lens; EFL=500mm 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 of 2mm at the edge, making it compact and robust. The effective focal length (EFL) of this lens is 500mm, providing a long focal length that can be beneficial in various settings.
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's geometry, with radii of curvature of 521.221508mm for both the front and back surfaces, ensures a high-quality image with minimal distortion.
The lens features broadband anti-reflection (BBAR) coating, designed to reduce reflection and increase transmission in the 400-700nm range. This coating enhances the lens's performance in a variety of lighting conditions and makes it suitable for use with a wide range of light sources.
