Variable Optical Delay Line (0 to 1200ps, SM, MM, PM)
Motor Driven Version
- Single piece with USB interface
- Wide delay range up to 1200ps
- All wavelength
- Low Cost
The MDTD Series Motor-driven Variable Optical Fiber Delay Lines provide precision optical delays of up to 1200 ps. They consist of two collimators and a movable reflector controlled by a precision step motor. Light from an input fiber collimator projects into free space and is collected by an output fiber collimator. The distance the light travels in free space is varied by the movable reflector.
The device is conveniently controlled by a computer via a USB cable interface. A graphic control software is provided.
