Fused Silica Bi-Concave Lens -- LUB-12.5-117.9-UV
from CVI Laser Optics

Bi-Concave or symmetric-concave lenses have a negative focal length and two concave surfaces with identical radii. Bi-concave lenses can be found in laser beam expanders, optical character readers, viewers, and projection systems. Bi-concave lenses diverge collimated incident light. They form... [See More]
