SLB-50B-120PIR1 50.0 mm Dia. x 121.3 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-50B-120PIR1 is a high-quality lens from OptoSigma, designed with a 50.0 mm diameter and a focal length of 121.3 mm. This lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and durability.
The lens features a double-convex geometry, with radii of curvature of 124.56 mm for both the front and back surfaces. This geometry, combined with the lens's high refractive index, provides excellent image quality and light gathering capabilities. The lens has a central thickness of 8 mm and an edge thickness of 3 mm, ensuring structural integrity and minimizing optical distortions.
The SLB-50B-120PIR1 is coated with Opt IR1 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 633-1064 nm wavelength range, making it ideal for a wide range of applications, including laser systems, bio-imaging, and machine vision.
