SLSQ-50.8B-80N 50.8 mm Dia. x -79.5 mm FL; Double-Concave Lens Uncoated

The SLSQ-50.8B-80N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 50.8 mm, is designed for use in a wide range of optical applications.

The lens features a base shape of a circle and is constructed from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The double-concave design, with radii of curvature of -73.6 mm for the first surface and 73.6 mm for the second, results in a back focal length of -80.5 mm. The edge thickness of the lens is 12 mm, while the center thickness is 3 mm, providing a robust and stable structure.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, especially where high transmission and low reflectivity are not critical.

The SLSQ-50.8B-80N is designed to work at a wavelength of 546.1 nm, making it suitable for use in a variety of applications that operate in this wavelength range. Its spherical shape ensures excellent image quality and low distortion, making it a reliable choice for various optical systems.
