SLB-50.8B-170PIR2 50.8 mm Dia. x 171.1 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-50.8B-170PIR2 is a 50.8 mm diameter, double-convex lens with a focal length of 171.1 mm, specifically designed for use within the wavelength range of 750-1550nm. 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 properties. The base shape of the lens is circular, and it features a spherical geometry with a thickness of 2.4 mm at the edge and 6.1 mm at the center. The effective focal length (EFL) is 171.1 mm, while the back focal length (BFL) is 169 mm. The radii of curvature for the first and second surfaces are 176.46 mm and -176.46 mm, respectively.
The SLB-50.8B-170PIR2 is coated with Opt IR2, a broadband anti-reflection coating that enhances its performance by reducing surface reflections. This coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission across the specified wavelength range.
