SLB-50.8B-50PIR2 50.8 mm Dia. x 52.7 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-50.8B-50PIR2 is a 50.8 mm diameter, double-convex lens with a focal length of 52.7 mm, specifically designed for use in the 750-1550nm wavelength range. This lens is sourced from OptoSigma, a renowned vendor in the optical industry.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and homogeneity. The base shape of the lens is circular, and it features a spherical geometry with a center thickness of 16.3 mm and an edge thickness of 3 mm. The effective focal length (EFL) is 52.7 mm, and the back focal length (BFL) is 47.1 mm.
The SLB-50.8B-50PIR2 is coated with Opt IR2, a broadband anti-reflection coating that enhances its performance in the infrared spectrum. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and improving transmission.
The lens is currently in stock and can be purchased directly from the vendor's website. With its high-quality materials, advanced coating, and precise geometry, the SLB-50.8B-50PIR2 is an excellent choice for a wide range of optical applications.
