SLSQ-20B-150P 20.0 mm Dia. x 150.5 mm FL; Double-Convex Lens Uncoated

The SLSQ-20B-150P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 20.0 mm and a focal length of 150.5 mm, is designed for use in a wide range of optical applications.

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 spherical geometry with a center thickness of 2.7 mm and an edge thickness of 2 mm. The radii of curvature for the first and second surfaces are 138 mm and -138 mm, respectively, resulting in a back focal length of 149.5 mm.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can exhibit higher levels of reflection, which may affect the performance in certain applications.

The SLSQ-20B-150P is designed for use at a wavelength of 546.1 nm. It is currently in stock and available for immediate purchase through the vendor's website.
