SLSQ-05B-20P 5.0 mm Dia. x 20.3 mm FL; Double-Convex Lens Uncoated
The SLSQ-05B-20P is a high-quality, double-convex lens offered by OptoSigma. This lens, with a diameter of 5.0 mm, is designed for use in a variety of optical applications. The lens features a focal length of 20.3 mm, making it suitable for systems that require a longer focal length.
The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it has a thickness of 1.2 mm at the edge and 1.5 mm at the center. The effective focal length (EFL) of the lens is 20.3 mm, and the back focal length (BFL) is 19.7 mm.
The SLSQ-05B-20P lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance at the air-glass interfaces, it also means that the lens is less susceptible to damage from environmental factors.
The lens is available from OptoSigma, and the provided web link indicates that it is currently in stock. This makes it an ideal choice for users who need a reliable and readily available optical component for their systems.
