Plano-Concave (PCV)Lenses, D=25.40mm, F=-150.00mm, UV UV Fused Silica, model 120301, is manufactured by United Optical Technology Co., Ltd.
UV Fused Silica Plano Concave (PCV) Lenses are plano-convex lenses based on fused silica.
UV fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass and has excellent transmittance in the ultraviolet band. It has a lower refractive index, better uniformity, smaller thermal expansion coefficient, higher chemical resistance and very low fluorescence, and can be used to make various optical components.

Plano-concave lenses will diverge light and have a negative focal length. One side is flat and the other side is concave. They are often used for beam expansion, projection and enlarging the focal length of optical systems.
It has a negative focal length and negative spherical aberration, which can be used to offset the aberrations of other lenses in the system.
