112-5530E 50.8 mm Dia. x -500 mm FL; Uncoated; Plano-Concave Lens

The 112-5530E is a plano-concave lens with a diameter of 50.8 mm and a focal length of -500 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 5.5 mm and a thickness center of 4 mm, indicating a slight curvature.

The lens is made of CAF2 (Calcium Fluoride) material, specifically the Mal-1963 variant, which is known for its excellent transparency in the ultraviolet region of the spectrum. The wavelength of 2940 nm suggests that this lens is designed for use in infrared applications.

Notably, this lens does not come with any coating, which means it is in its raw state. While this may make the lens more susceptible to environmental factors such as dust and scratches, it can also provide greater versatility in terms of customization. Users can apply their preferred coatings to suit their specific application needs.
