Profile: Optosigma Corp. deals with thin film coatings, optical components, and opto-mechanics. We have added motorized stages and systems, femtosecond mirrors, compact stepping motor actuators, and laser eye wear. We offer a wide range of anti-reflection coatings which may be applied to any of our glass or fused silica lenses or windows to reduce reflection losses. We provide a selection of high precision cylindrical lenses, both positive and negative, in glass and fused silica. These lenses are well suited for applications which require magnification in one dimension only.
