HO-PVL50-20C 50mm Dia. N-BK7 Plano-Concave Lens; EFL=-1000mm Single Layer MgF2
This HO-PVL50-20C optical lens, sourced from Holmarc Opto-Mechatronics, is a 50mm diameter Plano-Concave Spherical Lens with a single layer MgF2 coating. The lens is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. It has a planar (flat) surface on one side and a concave surface on the other, with a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -1000mm, making it a powerful tool for focusing or diverging light beams.
The lens features a single layer of MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the overall performance of the lens. The coating is applied at 0 degrees angle of incidence (AOI), ensuring uniform coverage and optimal performance.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.holmarc.com/plano_concave_lenses.php.
