Zinc Selenide (ZnSe) Double-Convex (DCX) Lenses

Double-Convex Lenses will focus light to a point. These lenses are made of two convex surfaces with equal radius. The focal length is positive. DCX Lenses are typically used in relay imaging systems or finite conjugate imaging systems. The larger the conjugate ratio, the larger the aberration in the imaging system . YZSY Optics offers uncoated or AR coating Double-Convex Lenses suitable for your application.
