PLCV-FS17 38 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens

The PLCV-FS17 is a plano-concave lens with a diameter of 38 mm and a focal length of -50 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 fused silica (mal-1965), a material known for its excellent optical properties, including high transparency across a wide range of wavelengths.

The lens geometry includes a thickness of 13.03 mm at the edge and 3 mm at the center, providing a robust structure while minimizing optical aberrations. The inner and outer radii are both 0, indicating a planar surface on one side and a concave surface on the other. The back focal length (BFL) is -52.07 mm, slightly longer than the effective focal length (EFL) due to the lens's concave design.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a higher risk of surface damage and lower light transmission compared to coated lenses, it also means that the lens is less prone to internal reflections, which can be beneficial in certain applications.
