Telecentric and Broadband Achromatic Objective Lens Systems
Achromatic lens systems with telecentric objectives enhance precision in optical coherence tomography for freeform surface metrology Institute Reference: 2-18091 Background Freeform optical components provide high performance but are challenging to measure with low uncertainty due to their complex shapes. Conventional metrology tools like Optical...
