40mm Diameter x 80mm FL NIR I Coated DCX N-K5 Lens for 600-1050nm Wavelength
This 40mm diameter x 80mm focal length lens, sourced from Edmund Optics, is a Spherical Lens of Sub Type Spherical (Convex-Convex) and Base Shape Circular. It boasts a geometry with a diameter of 40mm, a thickness edge of 3.07mm, a thickness center of 8mm, an effective focal length (EFL) of 80mm, a front radius (R1) of 82.29mm, a back radius (R2) of -82.29mm, and a back focal length (BFL) of 77.33mm. The lens does not have an Inner Radius or an Outer Radius.
The lens is made of N-K5 Schott material, a high-refractive index glass often used in optical systems requiring high numerical aperture (NA). It is designed to operate at a wavelength of 587.6nm. The lens features a front and back coating of EDM NIR-I STD CURVE, a broadband anti-reflection coating optimized for the near-infrared (NIR) spectrum, specifically for 600-1050nm wavelengths. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
