SLB-50-120PIR1 50.0 mm Dia. x 120.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-50-120PIR1 is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 120.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens geometry is characterized by a thickness edge of 3.0 mm and a thickness center of 8.2 mm. The inner and outer radii are 0 mm, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) is 120.0 mm, and the back focal length (BFL) is 114.6 mm. The curvature radius (R1) is 62.28 mm.
The lens is coated with opt ir1 on both the front and back surfaces, providing excellent anti-reflective properties within the wavelength range of 633-1064 nm. This coating enhances the lens's performance in infrared applications, reducing unwanted reflections and increasing transmission.
