G313374400 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm
The G313374400 is a high-quality double-concave lens from Qioptiq Photonics, designed with precision and performance in mind. This lens boasts a 12.7 mm diameter and a center thickness of 1.5 mm, making it a compact yet robust option for various optical applications.
The lens features a negative focal length (EFL) of -50mm, indicating its concave design. The radii of curvature for the front and back surfaces are -52.33mm and 52.33mm, respectively, contributing to its double-concave shape. The lens's inner and outer radii are both 0mm, further emphasizing its concave nature.
The lens is crafted from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility. It is specifically designed for use at a wavelength of 588nm, making it suitable for applications that require high transmission and low dispersion at this wavelength.
The G313374400 is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
