45-712-INK 40.0mm Dia. x 60.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-712-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm. The lens has a focal length (FL) of 60.0mm, making it suitable for a variety of optical applications.
The lens's geometry includes a thickness of 2.0mm at the edge and 9.31mm at the center. The front surface has a radius of curvature (R1) of 31.03mm, and the back focal length (BFL) is 53.9mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The 45-712-INK lens features a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR spectrum by reducing reflection and increasing transmission. The lens is inked, which aids in identifying the correct orientation during assembly.
