SKU: MDTD
The MDTD Series of Variable Optical Time Delay is a plug-and-play unit using a highly stable moving stage with a novel backlash prevention mechanism and incorporates proprietary optical encoders, offering submicron repeatability, long delay range, low loss, high speed, and compatibility with all wavelengths and all types of fibers, including SM, MM, and PM. It consists of two specially designed low-loss collimators, through which light from an input fiber is projected into free space, reflected by a movable retroreflector, and collected by an output fiber collimator. The variable time delay is achieved by adjusting the distance the light travels in free space. A precision step motor with adjustable speed moves the retroreflector. Conveniently, the device can be controlled via a computer using a shared Micro-B RS232 or USB interface, with graphical control software provided for intuitive operation.
The unit features an all-in-one design with integrated driving electronics housed inside, making it compact and easy to deploy.
The static minimum delay is determined by the physical length of the fiber cable. The dynamic minimum delay is defined by the stage resolution.
