SLSQ-30-120P 30.0 mm Dia. x 120.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-30-120P is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 120.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of fused silica, a material known for its excellent thermal stability and resistance to devitrification.

The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 4.1 mm, providing a base shape of a circle. The effective focal length (EFL) is 120.0 mm, and the radius of curvature (R1) is 55.2 mm. The back focal length (BFL) is 117.2 mm, and the inner and outer radii are both 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the material are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can suffer from increased reflection and reduced transmission, especially at larger angles or when used with broadband light sources.

The wavelength for this lens is 546.1 nm, and it is spherical in shape. The material ID is "fused sil mal-1965", providing a unique identifier for this specific type of fused silica.
