LC4924 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-20mm Uncoated
The LC4924 is a plano-concave spherical lens with a diameter of 12.7 mm and a center thickness of 2 mm. This lens is sourced from Thorlabs and is designed for use with a wavelength of 588 nm. The effective focal length (EFL) of this lens is -20 mm, indicating that it is a diverging lens, causing incoming light rays to spread out.
The lens is made from UVFS material with the ID 1965, which is a type of optical glass. The inner and outer radii of the lens are 0, indicating a plano surface on both sides. The lens's geometry is circular, making it suitable for a wide range of optical applications.
Notably, this 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 intended to be used without a coating.
