SLSQ-15-100N 15.0 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-15-100N is a Plano-Concave Lens with a diameter of 15.0 mm and a focal length of -100.0 mm, making it a negatively powered lens. 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, durability, and resistance to thermal shock.

The lens geometry includes an edge thickness of 2.6 mm and a center thickness of 2 mm, providing a robust structure. The inner and outer radii are both 0 mm, indicating a planar surface on one side and a concave surface on the other. The back focal length (BFL) is -101.4 mm, slightly longer than the effective focal length (EFL) due to the lens's concave shape.

This lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a wider range of wavelengths without the risk of coating damage or spectral shifts.

The lens is designed for use at a single wavelength of 546.1 nm, typically used in monochromatic applications. However, its uncoated nature allows for some flexibility in wavelength use, albeit with potentially higher reflective losses.
