PLCV501 50 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens

The PLCV501 is a plano-concave lens with a diameter of 50 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 transmission in the visible spectrum and excellent optical quality.

The lens geometry includes a thickness edge of 12.1 mm and a thickness center of 2 mm, providing a robust structure while minimizing unnecessary weight. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The back focal length (BFL) is -76.97 mm, slightly longer than the specified focal length, which can be beneficial in certain optical configurations.

The lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. This can be advantageous in applications where such coatings are not required or desirable, such as in certain laser systems. However, it should be noted that uncoated lenses can suffer from increased reflection at interfaces, which may affect system performance.

The lens is designed for use at a wavelength of 546.1 nm, typical for many visible light applications. However, it can also be used at other wavelengths, though this may affect its performance.
