All concave lenses diverge light, fused silica concave lenses are particularly useful for the UV region.

Good quality BK7 glass concave lenses are used to diverge light or sometimes to correct the image position in an optical system.

Plano Concave lenses have a negative focal length and the spherical aberration introduced into the wavefront by a plano concave lens is negative. As a result, it can be used to balance the positive spherical aberration introduced by other lenses.

This is the general standards we offer our customers, UNION OPTICS can supply other lenses meet your requirements, for detail information, please contact us.
