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

OptoSigma's SLSQ-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's base shape is circular, and it features a planar surface on one side and a concave surface on the other. The planar surface has an inner radius of 0 mm and an outer radius of 0 mm, while the concave surface has a radius of curvature (R1) of -46 mm. The back focal length (BFL) is -101.4 mm, and the effective focal length (EFL) is -100 mm.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency, low auto-fluorescence, and high resistance to thermal shock and chemical etching. The material's index of refraction at 546.1 nm is 1.4584.

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