SLSQ-20-120P 20.0 mm Dia. x 120.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-120P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 120.0 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.

The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 2.9 mm, providing a base shape that is circular. 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 118.0 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. It is designed to operate at a wavelength of 546.1 nm. The lens shape is spherical, which is a common type of lens used in various optical systems due to its simple design and manufacturing process.
