SLSQ-10B-20N 10.0 mm Dia. x -19.7 mm FL; Double-Concave Lens Uncoated
The SLSQ-10B-20N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use in various optical systems, features a spherical shape and is constructed from fused silica, a material known for its excellent optical properties and durability.
The lens has a diameter of 10.0 mm and a center thickness of 2.0 mm, with the edge being slightly thicker at 3.4 mm. The double-concave design, characterized by radii of curvature of -18.4 mm and 18.4 mm for the first and second surfaces, respectively, results in a back focal length of -20.3 mm. The effective focal length is -19.7 mm, making this lens suitable for applications requiring strong negative lensing.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens can be used in a wider range of wavelengths without the risk of coating damage. The lens is designed for use at a wavelength of 546.1 nm.
