The SLB-30B-40NM is a high-quality double-concave lens, designed with a base shape of a circle, and a diameter of 30.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for its precision optical components. The lens is constructed from n-bk7 schott material, a popular choice for its excellent optical properties.
The lens features a significant double-concave geometry, with a center thickness of 2.0 mm and an edge thickness of 7.6 mm. The effective focal length (EFL) of this lens is -39.7 mm, making it suitable for a wide range of optical applications. The radii of curvature for this lens are r1 = -41.52 mm and r2 = 41.52 mm, contributing to its double-concave structure.
The SLB-30B-40NM is coated with OptoM, a broadband anti-reflection coating that enhances its performance in the spectral range of 400-700 nm. This coating reduces surface reflections, improving the overall transmission of the lens.
