The SLB-05B-08P is a 5.0 mm diameter double-convex lens with a focal length of 8.4 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice 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 protect the surface.
The lens has a center thickness of 2.1 mm and an edge thickness of 1.4 mm, providing a good balance between weight and optical performance. The radii of curvature for the first and second surfaces are 8.3 mm and -8.3 mm respectively, indicating a strongly converging lens. The back focal length is 7.6 mm, which is the distance from the last surface of the lens to the focal point.
This lens is suitable for applications that require a compact, high-performance lens with a wide spectral range. It can be used in various fields such as imaging, beam shaping, and laser applications. However, due to its uncoated nature, it may not perform optimally in high-power or high-precision applications. Always ensure to check the lens's suitability for your specific application before purchasing.
