112-5111E 12.7 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens

The 112-5111E is a plano-concave lens with a diameter of 12.7 mm and a focal length of -75 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens's geometry includes a thickness edge of 3 mm and a center thickness of 2.4 mm, contributing to its overall concave shape.

The lens is made from CAF2 (Calcium Fluoride), a material with the Mal-1963 specification, which is known for its excellent transparency in the ultraviolet region of the spectrum. This makes the lens particularly suitable for applications that involve UV light, such as spectroscopy or UV imaging.

The lens does not come with any coating, which means it is uncoated. While uncoated lenses can suffice for many applications, they may be more susceptible to surface reflections and scattering, which can reduce the overall transmission and image quality. Therefore, depending on the specific application, a coating might be beneficial.

This lens is in stock and available for immediate purchase. For more information, including pricing and compatibility with your specific setup, please refer to the vendor's website, which is provided in the item data.
