HO-PVL25-12B 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-300mm BBAR 400-700nm
This is a Plano-Concave Spherical Lens, type HO-PVL25-12B, with a diameter of 25mm. It is sourced from the reputable vendor Holmarc Opto-Mechatronics, and is currently in stock, as indicated by its valid weblink status.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens's geometry includes a center thickness of 2.5mm, an effective focal length (EFL) of -300mm, and a radius of curvature (R1) of -156.485mm. The inner and outer radii are both zero.
The lens is designed to operate at a wavelength of 587.6nm. It features a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces, specifically designed for the wavelength range of 400-700nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall system's efficiency.
