HO-PVL12.5-04B 12.5mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm BBAR 400-700nm
This is a Plano-Concave Lens from Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. The lens, identified as HO-PVL12.5-04B, has a diameter of 12.5mm and a center thickness of 2.5mm. It is designed with a concave surface, which is characterized by a radius of curvature (R1) of -26.081mm. The lens's effective focal length (EFL) is -50mm, making it a negative lens.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material is known for its low dispersion and high Abbe number, making it suitable for a wide range of applications.
The lens features broadband anti-reflection (BBAR) coating on both surfaces, optimized for the wavelength range of 400-700nm. This coating reduces reflection and increases transmission, enhancing the lens's performance in various applications.
