HO-BXL25-02B 25mm Dia. N-BK7 Double-Convex Lens; EFL=50mm BBAR 400-700nm
This is the HO-BXL25-02B 25mm Dia. N-BK7 Double-Convex Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens is designed with a base shape of a circle and features a spherical geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 25mm and a thickness edge of 2mm, providing a robust and compact design. The effective focal length (EFL) of this lens is 50mm, making it a medium focal length lens. The first radius of curvature (R1) is 51.27334, and the second radius of curvature (R2) is -51.27334, indicating a double-convex lens design. The inner and outer radii are both 0, suggesting a symmetrical lens design.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range. The lens is designed to work optimally at a wavelength of 587.6nm.
The lens features a BBAR coating on both the front and back surfaces, specifically the Holmarc BBAR 0 AOI coating. This coating enhances the lens's performance by reducing reflection and increasing transmission across the 400-700nm wavelength range.
