G314002400 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm
The G314002400 is a Plano-Concave lens with a diameter of 8 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 features a center thickness of 1 mm and an effective focal length (EFL) of -8 mm, making it suitable for applications that require a concave lens.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The curvature of the concave surface is defined by a radius of -4.134 mm.
This lens is designed to operate at a wavelength of 588 nm and comes with a front and back coating of Qio Silver RAGV 45. This coating enhances the lens's performance by reducing reflection and increasing transmission. The lens's shape is spherical, which is a common choice for its ease of manufacturing and good optical performance.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
