38-397 12.5mm Dia. x 12.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 38-397 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 12.5mm and a thickness at the edge of 2.08mm, while the center thickness is 2.5mm. The effective focal length (EFL) of this lens is 84, making it suitable for a variety of optical applications.
The lens's front and back surfaces are coated with edm nir-ii std curve, a specialized coating designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating enhances the lens's performance in the NIR range, making it an ideal choice for applications that require superior optical transmission in this spectrum.
The lens is made of n-bk7 schott, a high-quality optical glass known for its excellent optical properties, including high transmission in the visible and near-infrared regions, low auto-fluorescence, and high chemical resistance. This material ensures the lens delivers reliable and consistent performance.
