HO-PVL50-1.6C 50mm Dia. N-BK7 Plano-Concave Lens; EFL=-80mm Single Layer MgF2
This HO-PVL50-1.6C Plano-Concave Lens, sourced from Holmarc Opto-Mechatronics, is a spherical lens with a base shape of a circle. It has a diameter of 50mm and a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -80mm, making it a negative or diverging lens. The radius of curvature (R1) is -41.729mm, and both the inner and outer radii are 0mm, indicating a plano surface on one side and a concave surface on the other.
The lens is made of N-BK7, a popular glass type in the Schott catalog, known for its excellent optical properties. It is designed to work at a wavelength of 587.6nm. The lens features a single layer of MgF2 coating on both the front and back surfaces, which is indicated by 'hol mgf2 0 aoi'. This coating is intended to reduce reflection and increase transmission, enhancing the lens's performance in its intended application.
The lens is currently in stock and available for purchase through the Holmarc Opto-Mechatronics website, as indicated by the 'weblink status: Valid - in stock' field in the item data. For more information, users can refer to the provided weblink.
