Fiber Optic High Resolution Variable Mini Optical Delay Line – Motor Driven

SKU: MDTD

The MDTD Series of Variable Optical Time Delay uses 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 type 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 USB cable interface, with graphical control software provided for intuitive operation.
