SLB-20B-150PIR1 20.0 mm Dia. x 150.4 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-20B-150PIR1 is a high-quality lens from OptoSigma, designed with a 20.0 mm diameter and a focal length of 150.4 mm. This lens is made from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a double-convex geometry, with radii of curvature of 155.7 mm for the first surface and -155.7 mm for the second. This specific shape, combined with the lens's high refractive index, allows for efficient light bending and focusing. The lens has a thickness of 2 mm at the edge and 2.6 mm at the center, providing robustness and durability.
The SLB-20B-150PIR1 comes with a broadband anti-reflection coating, Opt IR1, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission in the 633-1064 nm spectral range, making it ideal for a wide range of applications, including laser systems and imaging applications.
