L-PCC053 12.7 mm Dia. Plano-Concave Lens; EFL=-25mm Uncoated

The L-PCC053 is a plano-concave lens with a diameter of 12.7 mm, making it suitable for applications requiring compact optical components. The lens's base shape is circular, contributing to its space-efficient design.

The lens's geometry is spherical, with a center thickness of 2.5 mm and an effective focal length (EFL) of -25 mm. The negative EFL indicates that this is a diverging lens, which spreads out light rays. This can be useful in various applications, such as beam expanders or in systems where light needs to be distributed over a larger area.

The lens is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The wavelength for which the lens is designed is 587.6 nm, which is in the visible light spectrum.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, an uncoated lens can be advantageous in certain applications where specific coating properties are not required, or to minimize cost.
