Optical Tolerance Analysis Black Book: From “Failure Scene” to “Successful First Prototype”, A Must-Have Fault-Tolerant Design Guide for Engineers
“Theoretically no problem, but the processing is a complete mess” – this phrase is a nightmare for many optical engineers. Three years ago, a high-end surveillance lens designed by my team fell into this pit: the theoretical MTF value was close to the diffraction limit, yet the yield of the first batch of samples was … Read more
