The Measuring Division of Kaman Precision Products, Inc. offers its KD-5100 differential measurement system, which provides resolution to a nanometer of positional change. With its proven stable design, extremely small size, and low power consumption, it is ideal for night vision systems, precision telescope positioning, fast steering mirrors (FSM) for space-based and airborne applications, and image stabilization systems. Measuring only 2 x 2.12 x 0.75 inches thick, it features rugged construction, with a mean time between failures of better than 238,000 hours in a space flight environment and 55,000 hours in a tactical environment. Kaman also offers the DIT-5200, a commercial version of the KD-5100 for applications where mil-spec requirements, size, weight and power consumption are not critical.
