Variable optical delay line

In order to precisely control the optical path delay, a variable optical delay line was designed. Based on optical calibration technology. Variable delay lines provide air path variations of up to 50, 100, 200, and 400mm, corresponding to optical delays of up to 165, 330, 660, and 1300ps, respectively. There are two versions available: electric and manual. It is an ideal solution for network equipment, testing instruments, and laboratory testing applications.
