L-PCC027 12.7 mm Dia. Plano-Concave Lens; EFL=-75mm Uncoated

The L-PCC027 is a plano-concave lens with a diameter of 12.7 mm, making it suitable for applications requiring compact optical components. The lens features a center thickness of 2.5 mm and an effective focal length (EFL) of -75 mm, indicating its diverging nature. This type of lens is often used in applications where beam divergence is required.

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 glass has a refractive index of approximately 1.5168 at the specified wavelength of 587.6 nm.

The geometry of the lens is spherical, with a radius of curvature (R1) of -38.76 mm for the concave surface. The lens does not have an inner or outer radius, indicating that it is a simple plano-concave design.

Notably, this lens is uncoated. While uncoated lenses can be more cost-effective, they may be more susceptible to surface reflections and scattering, which can reduce transmission and introduce unwanted artifacts. Coatings can be applied to enhance the performance of the lens, but this is not specified in the item data.
