"WebAn f-theta lens permits an optical lines scans at a reasonably constant speed which keeps the time between laser dots somewhat constant. Without an f-theta the electronics would need to compensate for a variable time between dots to prevent image distortion. So particularly in the days of analog electronics, f-theta lenses were great for taking ... " - F theta lens 原理
