Production and testing of precision plastics optical components

摘要

Abstract: The aspheric lens has developed over many years to meet the needs of industry. Refinement in curve mathematics, methods of die surface generation, methods of moulding, up-to-date measurement techniques and mounting methods have led to the capability to produce lens elements with diffraction limited capability at economical cost. Such lenses are produced in wavelength ranges covering visible, near infrared and med infrared. An ever widening range of products is served, and the flexibility of plastics leads us to believe that many more are possible, at cost levels unobtainable by other techniques.!0
