The SLB-40-80PIR2 is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 80.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a material known for its excellent optical properties.
The lens geometry is characterized by its edge thickness of 2.0 mm and center thickness of 7.1 mm. The effective focal length (EFL) is 80.0 mm, and the radius of curvature (R1) is 41.52 mm. The back focal length (BFL) is 75.3 mm, and both the inner and outer radii are 0 mm.
The SLB-40-80PIR2 is coated with Opt IR2 on both the front and back surfaces, making it suitable for use in the 750-1550nm wavelength range. This coating enhances the lens's performance by reducing reflection and increasing transmission.
