Motor Driven Variable Optical Time Delay0 to 600ps range with 1fs resolution
The Motor Driven Variable Optical Time Delay features fast speed and high accuracy. It consists of two collimators and a movable reflector controlled by a precise step motor. Light from input fiber collimator projects into free space and is collected by the output fiber collimator. The distance the light travels in free space is varied by the movable reflector. The driving circuit is connected to the computer through RS232 or USB interface for operation. We offer graphic control interface.
