As early as 1968, Scientech became the leader in the design and manufacture of laser power and energy measurement instruments. Scientech provides high-quality and high-precision laser power measurement equipment for specialized markets such as laboratories, analysis, and industry. As a pioneer in the laser power and energy measurement instrument industry, our power detectors range from microwatts to megawatts.

Light has no mass, but it has momentum. When light collides with an object, a small amount of force is generated, which is called 'light pressure'. The force generated by a 100KW laser beam is about 330mg, which is equivalent to the weight of several grains of coarse sand. The NIST Scientech team utilizes this principle to shine laser onto high reflectivity lenses and convert the force measurement on the lenses into laser power measurement.

This instrument has become NIST's standard reference instrument for measuring power above 1KW. Unlike traditional heat dissipation thermoelectric power meters, this new device can measure in real-time: after the light hits the high reflectivity lens, it can be directly used for cutting, welding and other applications, with fast response, no need for water cooling, and convenient integration. It is an ideal choice for quality control of laser applications in material processing. We currently offer two products: one for direct power measurementRPPM(Optical pressure power meter) and those used for material processing and integrated applicationsMPPM(Material processing power meter).
