Positive cylindrical lenses are ideal for applications requiring magnification in one dimension. A typical application is to use a pair of cylindrical lenses to provide anamorphic shaping of a beam. A pair of positive cylindrical lenses can be used to collimate and circularize the output of a laser diode. Another application possibility would be to use a single lens to focus a diverging beam onto a detector array. These CaF₂ Plano-Convex Cylindrical lenses are available uncoated or with an antireflection coating optimized at 3~5μm.
