14PCV500-1-2 25.4 mm Dia. x -500 mm FL; Uncoated; Plano-Concave Lens

This is a Plano-Concave Lens from Standa, a renowned vendor in the optical industry. The lens, identified as 14PCV500-1-2, has a diameter of 25.4 mm and a center thickness of 3.7 mm, with the edge thickness being slightly larger at 4 mm. The effective focal length (EFL) of this lens is -500 mm, indicating that it is a diverging lens, causing incoming light rays to spread out.

The lens is made from UVFS Mal- 1965, a material specifically designed for use in the ultraviolet region of the spectrum, with a wavelength of 355 nm. This makes it ideal for applications that require the manipulation of ultraviolet light, such as in scientific research or industrial processes.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the lens material are desired, or where cost is a significant factor. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust, dirt, and moisture, which can affect their performance.

The lens's geometry is spherical, with a base shape that is circular. The inner and outer radii are both zero, indicating that the lens does not have any curvature on its inner or outer edges. This, combined with its Plano-Concave design, makes it a versatile lens that can be used in a wide range of optical systems.
