G314323400 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm
The G314323400 is a plano-concave lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is made from N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. The lens's concave shape, characterized by a negative focal length (EFL=-200mm), is designed to diverge light rays.
The lens's geometry includes a center thickness of 1.5 mm and an inner radius of 0 mm, with no specified outer radius. The curvature of the lens is defined by a radius (R1) of -104.41 mm. This spherical lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its reflective properties.
The lens operates at a wavelength of 588 nm, making it suitable for applications that utilize this wavelength. The lens is available from Qioptiq Photonics and is currently in stock, according to the vendor's website.
