SLSQ-10-50N 10.0 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-10-50N is a plano-concave lens with a diameter of 10.0 mm and a focal length of -50.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is made of fused silica, a material known for its excellent optical properties and durability.

The lens's geometry is characterized by its edge thickness of 2.6 mm and center thickness of 2 mm. 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 -51.4 mm, slightly longer than the specified focal length, which is typical for plano-concave lenses.

The SLSQ-10-50N is uncoated, meaning it does not have any anti-reflective or other surface coatings. This can be advantageous in certain applications where the natural properties of the lens material are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can exhibit higher levels of surface reflection, which may need to be accounted for in the design of the optical system.

This lens is designed to operate at a wavelength of 546.1 nm, which is in the green portion of the visible spectrum. It is spherical in shape, a common and versatile geometry for many optical applications.
