G063873322 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-200mm 450-700nm
This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -200mm and designed for use within the wavelength range of 450-700nm. The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity and excellent optical transmission properties.
The lens's geometry includes a center thickness of 1.5mm, with an inner radius of 0mm and an outer radius of 0mm, indicating a purely concave shape. The concave surface has a radius of curvature of -104.41mm.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces, enhancing its performance in the visible spectrum. This coating is designed to reduce reflection and improve transmission, making it suitable for applications that require high light transmission and low loss, such as imaging systems, beam shaping, and laser applications.
The lens is mounted, providing convenience and ease of use. According to the vendor's website, the item is currently in stock, making it readily available for immediate use.
