SLB-30B-150PM 30.0 mm Dia. x 150.6 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-30B-150PM is a high-quality lens from OptoSigma, designed for use in the 400-700nm wavelength range. This lens is a spherical, biconvex design, featuring a 30.0 mm diameter and a focal length of 150.6 mm. The lens is made from n-bk7 Schott glass, a popular material due to its excellent optical properties and wide transparency range.
The lens has a center thickness of 3.4 mm and an edge thickness of 2 mm, providing robustness and durability. The inner and outer radii are 0 mm, indicating a symmetrical design. The effective focal length (EFL) is 150.6 mm, and the back focal length (BFL) is 149.4 mm.
The SLB-30B-150PM is coated with OptoSigma's proprietary Opt M coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving image quality and contrast.
