PLCV204 25.4 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens

The PLCV204 is a plano-concave lens with a diameter of 25.4 mm and a focal length of -75 mm, sourced from WTS Photonics. This lens is designed for use in optical systems where a negative focal length is required. The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity and excellent transmittance in the visible spectrum.

The lens has a central thickness of 2 mm and an edge thickness of 4.13 mm, providing structural integrity and resistance to deformation. The plano-concave shape, with a radius of curvature of -38.9 mm, ensures a well-defined optical path for light rays passing through the lens. The back focal length of -76.31 mm indicates the distance from the lens's rear surface to the focus point.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in higher reflective losses and increased susceptibility to environmental damage, it also means the lens can be easily integrated into existing optical systems without concerns about coating compatibility.
