14PCX250-1-3 25.4 mm Dia. x 250 mm FL; Uncoated; Plano-Convex Lens

This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa, a reputable vendor in the optical industry. The lens is characterized by its circular base shape and is designed for use in various optical systems.

The lens has a diameter of 25.4 mm and a thickness of 3 mm at the edge, while the center thickness is 3.8 mm. The effective focal length (EFL) of the lens is 250 mm, making it suitable for applications that require a long focal length. The lens's inner and outer radii are both 0, indicating a plano-convex geometry.

The lens is made from CAF2 (Calcium Fluoride) material, specifically the mal-1963 variant. This material is known for its excellent transparency in the infrared region, making it ideal for applications in this spectrum. The lens is designed to operate at a wavelength of 2940 nm.

Notably, this lens does not have any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors. However, uncoated lenses can be advantageous in certain scenarios, such as when cost or simplicity is a primary concern.
