HO-PVL25-1.6B 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm BBAR 400-700nm
This is a Plano-Concave Spherical Lens, type HO-PVL25-1.6B, with a diameter of 25mm. It is sourced from the reputable vendor Holmarc Opto-Mechatronics. The lens is made of N-BK7 Schott material, a popular choice for its excellent optical properties. The lens's geometry includes a center thickness of 2.5mm and an effective focal length (EFL) of -40mm, making it suitable for a variety of optical applications.
The lens's inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The curvature of the concave surface is specified as -20.865mm. The lens is designed to operate at a wavelength of 587.6nm.
The lens features broadband anti-reflection (BBAR) coating on both the front and back surfaces, optimized for the wavelength range of 400-700nm. This coating reduces reflection and increases transmission, enhancing the lens's performance in various applications.
