PLCV-FS20 38 mm Dia. x -200 mm FL; Uncoated; Plano-Concave Lens
The PLCV-FS20 is a plano-concave lens with a diameter of 38 mm and a focal length of -200 mm, making it a negatively powered lens. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 4.98 mm, while the center thickness is 3 mm. The back focal length (BFL) is -202.11 mm, and the effective focal length (EFL) is -200 mm. The radius of curvature (R1) is -92.04 mm. The lens does not have an inner or outer radius, indicating that it is a flat lens on one side and curved on the other.
The lens is made of fused sil mal-1965, a type of optical glass. The wavelength of operation is 633 nm. This lens is a spherical lens, meaning it has a spherical surface on both sides.
