SLSQ-25-90N 25.0 mm Dia. x -90.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-25-90N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens is designed with a base shape of a circle and is uncoated. The lens is fabricated from fused silica, a material known for its excellent thermal stability and chemical resistance.

The lens has a diameter of 25.0 mm and a thickness at the edge of 3.9 mm. The center thickness is 2 mm. The effective focal length (EFL) of this lens is -90.0 mm, indicating that it is a diverging lens. The radius of curvature (R1) is -41.4 mm, and the back focal length (BFL) is -91.4 mm. The lens does not have any inner or outer radius.

This lens is designed to operate at a wavelength of 546.1 nm. The lens is not coated, which means it does not have any anti-reflective or other surface treatments. This may result in higher reflective losses and a lower overall transmission compared to coated lenses. However, uncoated lenses are often preferred in applications where the coating might introduce unwanted optical effects or where cost is a significant factor.

The lens is currently in stock and available for purchase through the vendor's website.
