G063875400 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-1000mm
This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -1000mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties.
The lens's geometry includes a center thickness of 1.5mm, and its curved surface has a radius of curvature (R1) of -523.3mm. 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 lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which is a broadband anti-reflection coating designed to reduce surface reflections and increase transmission.
This lens is a spherical lens, meaning it has a spherical curvature, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
The lens is in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
