The SLB-30B-250PIR1 is a high-quality lens from OptoSigma, designed with a 30.0 mm diameter and a focal length of 250.5 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 259.5 mm and -259.5 mm for the first and second surfaces, respectively. This geometry results in a back focal length of 249.5 mm.
The lens has a thickness of 2 mm at the edge and 2.9 mm at the center, providing robustness and stability. The coating on both the front and back surfaces is opt ir1, which is optimized for the wavelength of 546.1 nm. This coating enhances the lens's performance by reducing reflection and increasing transmission.
The SLB-30B-250PIR1 is currently in stock and available for immediate purchase from the OptoSigma website. Its combination of high-quality materials, precise geometry, and advanced coating make it an excellent choice for a wide range of optical applications.
