UM OPTICS CaF2 BaF2 MgF2 BK7 Fused silica Ge Si ZnSe ZnS Plano-Concave Lens
Description
Plano-concave lens with one concave side and one flat side can spread the light out and has a negative focal length. Plano-concave lenses are often used for beam extension, projection and focal length expansion of optical systems. The plano-concave lenses has a negative focal length and negative spherical aberration, which can be used to offset the aberration of other lenses in the system. To obtain a smaller spherical aberration, the collimated beam should be incident on the concave side of the plano-concave lenses when the incident beam is collimated.
