Description
Double Concave Lenses are used in beam expansion, image reduction, or light projection applications. These
lenses are also ideal for expanding the focal length of an optical system. Double Concave Lenses, which have
two concave surfaces, are Optical Lenses with negative focal lengths. Uni-Optics offers Double Concave lenses
with a variety of coating options.
