25mm Dia. x 125mm FL VIS-NIR Coated UV Double-Convex Lens
This 25mm diameter x 125mm focal length VIS-NIR coated UV double-convex lens is a high-quality optical component sourced from Edmund Optics. It is designed for use in the visible to near-infrared spectrum, specifically covering the 400-1000nm range.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is characterized by its "biconvex" shape, which provides a wide range of applications, including imaging, illumination, and beam shaping. The lens has a diameter of 25mm and a thickness of 2.05mm at the edge, while the center thickness measures 3.42mm. The effective focal length (EFL) is 125mm, and the back focal length (BFL) is 123.82mm.
The lens is made from fused silica, a material with a high transmission range, making it suitable for use in various applications. It is coated with a VIS-NIR coating, identified as "edm visnir0sp2002000" on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the specified wavelength range.
