SLSQ-15-90N 15.0 mm Dia. x -90.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-15-90N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens is uncoated and features a fused silica material (fused sil mal-1965) with a diameter of 15.0 mm and a focal length of -90.0 mm. The lens's base shape is circular, and it has a plano-concave geometry, meaning one side is flat (plano), and the other side is curved inward (concave).

The lens's thickness at the edge is 2.7 mm, while the center thickness is 2.0 mm. 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, indicating a uniform curvature.

The SLSQ-15-90N is designed to operate at a wavelength of 546.1 nm. It is essential to note that this lens is uncoated, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors. Always ensure the lens's specifications align with your application's requirements.
