Proceedings PaperPractical Aspects Of The Use Of Optical Test Methods In Production
|Format||Member Price||Non-Member Price|
Optical testing in production is becoming increasingly complex as component specific-ations become tighter. It is no longer satisfactory to evaluate lenses by the visual appearance of the image they produce and objective test methods are becoming more commonly used in the optical workshop. The most important objective test parameters to be considered are optical transfer function, transmission, distortion and veiling glare. Most of the comments which follow relate specifically to m t f but also in a general sense to all optical measurements.
