Manual Variable Optical Delay Line

(0 to 1200ps, SM, PM, Bidirectional)
  • Precision display with an optical encoder
  • Wide delay range up to 1200ps
  • All wavelength
  • Low Cost

The Manual Variable Optical Time Delay features long rang up to 1200 ps and low cost.  It consists two collimators and a movable reflector controlled by a precision manual stage. 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 and displayed digitally with a position encoder.
