SLB-30-200P 30.0 mm Dia. x 200.0 mm FL; Plano-Convex Lens Uncoated
The SLB-30-200P is a 30.0 mm diameter, plano-convex lens with a focal length of 200.0 mm, sourced from OptoSigma. This lens is made of n-BK7 Schott glass, a popular material for its high refractive index and low dispersion. The lens is uncoated, which means it does not have any additional layers to enhance light transmission or reduce reflection.
The lens has a center thickness of 3.1 mm and an edge thickness of 2 mm. The radius of curvature of the curved surface is 103.8 mm, and the back focal length is 198 mm. The effective focal length (EFL) is the same as the focal length, at 200 mm. The lens has no inner or outer radius, indicating a uniform curvature.
This lens is suitable for use in a wide range of applications, including imaging, beam shaping, and laser systems. However, the lack of coating may make it less suitable for high-precision applications that require low reflectivity or high transmittance. The lens is currently in stock and can be purchased directly from the vendor's website.
