45-490-INK 12.0mm Dia. x 100.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-490-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the VIS-NIR range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The lens's geometry is characterized by a thickness of 2.15mm at the edge and 2.5mm at the center. It has a focal length (EFL) of 100mm and a front radius (R1) of 51.68mm. The back focal length (BFL) is 98.35mm, and the lens has no inner or outer radius, indicating a plano surface on the back.
This lens is made of n-bk7 schott, a popular optical glass known for its excellent optical properties and versatility. The material is characterized by a high refractive index and low dispersion, making it suitable for a wide range of applications.
