14PCV80-05-2 12.7 mm Dia. x -80 mm FL; Uncoated; Plano-Concave Lens

The 14PCV80-05-2 is a plano-concave lens with a diameter of 12.7 mm and a focal length of -80 mm, making it a negatively powered lens. This lens is sourced from Standa, a reputable vendor in the optical industry, and is available for purchase on their website.

The lens is made of UVFS Mal- 1965, a material with a specific refractive index that influences how light passes through it. The lens's geometry includes a thickness of 3 mm at the edge and 2.5 mm at the center, with no inner or outer radius specified, indicating a simple plano-concave shape.

This lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can make it more susceptible to environmental factors such as dust, moisture, and scratches, but it also means that it does not introduce any additional chromatic aberration or other optical distortions that coatings can sometimes cause.

The lens is designed to operate at a wavelength of 355 nm, which is commonly used in various applications such as laser systems and fluorescence microscopy. It is important to note that the lens's performance can vary depending on the specific conditions of its use, including the angle of incidence, the numerical aperture, and the spectral bandwidth of the light passing through it.
