SLSQK-30-100N 30.0 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQK-30-100N is a fused silica plano-concave lens, uncoated and designed for general use. This lens boasts a diameter of 30.0 mm and a focal length of -100.0 mm, making it suitable for a wide range of optical applications.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency, low auto-fluorescence, and resistance to thermal shock. The material's index of refraction is 1.458 at 546.1 nm, which is the wavelength used for specifying the lens's parameters.

The SLSQK-30-100N features a base shape of circular and a geometry that includes a thickness edge of 4.5 mm and a thickness center of 2 mm. The lens's inner and outer radii are both 0 mm, and its back focal length is -101.4 mm. The curvature of the lens is spherical, with a radius of curvature (R1) of -46 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses, it also means the lens is less susceptible to damage from environmental factors or handling.

According to the vendor's website, this lens is currently in stock, making it a readily available option for those in need of a high-quality, plano-concave lens.
