SLSQ-50.8-70P 50.8 mm Dia. x 70.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-50.8-70P is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 70.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens geometry is characterized by its base shape, which is circular, and its geometry, which includes a diameter of 50.8 mm, a thickness edge of 2.5 mm, and a thickness center of 14.9 mm. The effective focal length (EFL) is 70.0 mm, and the radius of curvature (R1) is 32.2 mm. The back focal length (BFL) is 59.8 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the natural properties of the material are desired, or where cost is a consideration. However, it's important to note that uncoated lenses can suffer from increased reflection, which can reduce transmission and introduce unwanted artifacts into the optical system.

The lens is designed to operate at a wavelength of 546.1 nm. It is spherical in shape, which is a common and versatile lens shape suitable for a wide range of applications.
