Zinc Selenide (ZnSe) Double-Concave (DCV) Lenses
Double-Concave Lenses can diverge the light, its focal length is nedtive, which is made of two concave surfaces with same radius.These lenses are ideal for the application of beam expansion, light projection or the expansion of the focal length. Grand Unified Optics offers uncoated or AR coatings Double-Concave Lenses for your appliation.
