This is a Plano-Convex Lens from Standa, a renowned vendor in the optical industry. The lens, identified as 14PCX50-05-3, has a diameter of 12.7 mm and a focal length of 50 mm, making it suitable for a wide range of optical applications.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a thickness of 2 mm at the edge and 3 mm at the center. The inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 50 mm, which is the distance from the lens's principal point to the focal point.
The lens is made of CAF2 (Calcium Fluoride) material, specifically the mal-1963 variant. This material is known for its excellent transparency in the ultraviolet region, making it ideal for applications that involve UV light. The wavelength for this lens is 2940 nm.
Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other beneficial properties. However, this lens does not have any coatings, which may be suitable for certain applications where coatings are not required or desirable.
The lens is currently in stock and available for purchase. For more information, you can refer to the vendor's website at http://www.standaphotonics.com/lenses/plano-convex-lenses.php.
