SLSQ-50.8B-120P 50.8 mm Dia. x 121.5 mm FL; Double-Convex Lens Uncoated
OptoSigma's SLSQ-50.8B-120P is a high-quality, double-convex lens with a diameter of 50.8 mm and a focal length of 121.5 mm. This lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.
The lens features a base shape of a circle and a geometry that includes an edge thickness of 2.8 mm and a center thickness of 8.7 mm. The effective focal length (EFL) is 121.5 mm, while the back focal length (BFL) is 118.5 mm. The first and second radii of curvature (R1 and R2) are 110.4 mm and -110.4 mm, respectively.
This lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance loss, it also means that the lens can be used in a wider range of applications without the risk of coating damage.
The SLSQ-50.8B-120P is designed for use at a wavelength of 546.1 nm. It is a spherical lens, which is the most common type of lens due to its ease of manufacturing and versatility.
