TELECENTRIC REFLECTION HEAD FOR OPTICAL MONITOR |
摘要 |
The use of a telecentric system allows for minimizing the changes in the measured radiometric quantity as a result of defocus or tilt of the object under measurement or of the detector. In a preferred embodiment, a telecentric illuminating system is provided, which illuminates an object from a source. A telecentric receiving system receives reflections from the object and relays them to a detector. In another preferred embodiment, a telecentric system is also described that is appropriate for radiance or radiant intensity measurements.
