SLB-50B-100PIR1 50.0 mm Dia. x 101.5 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-50B-100PIR1 is a high-quality lens offered by OptoSigma, designed with a 50.0 mm diameter and a focal length of 101.5 mm. This lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and versatility.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards, which is ideal for applications requiring a wide range of wavelengths, as in this case, between 633 and 1064 nm. The radii of curvature for the first and second surfaces are 103.8 mm and -103.8 mm, respectively, contributing to its superior light-bending capabilities.
The lens has an edge thickness of 3 mm and a center thickness of 9.1 mm, providing robustness and durability. The back focal length (BFL) is 98.5 mm, which is the distance between the lens's rear surface and its principal plane. The inner and outer radii are both 0, indicating a uniform curvature across the lens's surface.
The SLB-50B-100PIR1 comes with a front and back coating of opt ir1, enhancing its performance by reducing reflection and increasing transmission. This lens is an excellent choice for applications requiring a high-performance, broadband lens with precise specifications.
