112-5115E 12.7 mm Dia. x -100 mm FL; Uncoated; Plano-Concave Lens

The 112-5115E is a plano-concave lens with a diameter of 12.7 mm and a focal length of -100 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 thickness center of 2.5 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 falls within the infrared region, suggesting that this lens may be used in infrared applications. However, the coating parameter is an empty object, indicating that this particular lens is uncoated.

This lens is part of the spherical lens category, which is characterized by a surface that curves in one direction along a single axis. The base shape is circular, which is a common shape for optical elements. The inner and outer radii are both zero, suggesting that the curvature is consistent throughout the lens.

The lens's web links are valid and indicate that it is in stock, making it readily available for purchase. The detailed parameters and specifications provided in the item data can assist users in determining whether this lens meets their specific requirements.
