WebOur mulitple locations allow us to leverage a nationwide network and maintain the … WebWhile f-theta lenses are well designed to provide a flat image plane, a real lens rarely measures up to the theoretical. There will be some amount of distortion and curvature. Figure 2 shows these parameters for our FTH100-1064 f-theta lens, where focal length is 100 mm and the maximum deflection angle is 28°. tacc thanksgiving
