This is a Plano-Concave Lens from Standa, a renowned vendor in the optical industry. The lens, identified as 14PCV5000-1-2, has a base shape of Circular and is designed for Spherical geometry. It features a diameter of 25.4 mm and a thickness of 2 mm at the edge and center.
The lens has an effective focal length (EFL) of -5000 mm, indicating its diverging nature. The radius of curvature (R1) is -2380.5 mm, and the inner and outer radii are 0 mm, suggesting a plano surface on one side and a concave surface on the other.
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 transmission of ultraviolet light.
Please note that the lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, in this case, the lens is in its bare form, offering the basic optical properties of the material and geometry.
The lens is currently in stock and available for immediate purchase. For more information, you can refer to the vendor's website provided in the item data.
