SLSQ-10B-20P 10.0 mm Dia. x 20.6 mm FL; Double-Convex Lens Uncoated
The SLSQ-10B-20P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 10.0 mm and a focal length of 20.6 mm, is designed for use in a variety of optical systems.
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 features a double-convex geometry, with radii of curvature of 18.4 mm for the first surface and -18.4 mm for the second surface. This geometry results in a back focal length of 19.4 mm.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the lens material are desired. However, it's important to note that uncoated lenses can exhibit higher levels of reflection, which may need to be considered in the design of the optical system.
The SLSQ-10B-20P is designed for use at a wavelength of 546.1 nm. It has a center thickness of 3.4 mm and an edge thickness of 2 mm. The lens is available for purchase through the OptoSigma website, where it is listed as being in stock at the time of writing.
