SLSQ-20-90P 20.0 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-90P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 90.0 mm, sourced from the reputable vendor OptoSigma. This 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 20.0 mm, a thickness edge of 2.0 mm, and a thickness center of 3.2 mm. The effective focal length (EFL) is 90.0 mm, and the radius of curvature (R1) is 41.4 mm. The back focal length (BFL) is 87.8 mm, and both the inner and outer radii are 0 mm.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This may be suitable for applications where the light does not need to be reflected or transmitted in a specific way. However, for applications that require specific light behavior, coatings can be applied to enhance the lens's performance.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of optical applications. Its spherical shape ensures that light rays are focused to a single point, making it ideal for use in imaging systems, beam shaping, and other applications where light focusing is required.
