VDL-001 Manual Variable Optical Delay Line
The VDL-001 family of manual variable optical delay lines provides optical path length adjustment of up to 600 ps in single-pass configuration.
The VDL-001 is a fiber coupled delay line with the delay adjustment path in free space. The delay is adjusted by manually turning a handle on one end of the device, and position is read from a vernier scale on the side. The delay line is available with either single mode or PM fiber pigtails.
