Optical gratings


CEKO technology is based on state-of-the-art optical MEMS technology, known as refractive index modulation™ (RIM), improving the reliability and applicability of CEKO sensors to a level beyond any other optical sensor technology.

Sensors are fabricated using nanoscale cleanroom production technology for mass-production and minimum cost, making it possible to create millions of opto-mechanical structures with a feature size less than 1/1000th of a human hair in one go.

Conventional MEMS sensors are based on electrical signals, hence they contain metal or other electrical conducting materials. The CEKO sensors are a unique kind of MEMS sensors without metal at all, making them even more versatile and robust than other MEMS sensors.


The refractive index modulation technology found in our sensors represents a new era in sensing possibilities. Remote sensing, distributed sensing, large sensor networks, high temperature sensing and metal-free sensing is now simple, reliable and with a sensitivity not seen before.

With the advanced sensors from CEKO it is possible to do high quality measurements in difficult accessible and harsh environments, such as oil and gas wells, wind turbines, on air foils, in strong electromagnetic fields or areas that present an explosion risk such as fuel tanks or gas storages.

Making optical sensing technology easy, fast, robust and cost-efficient is with refreactive index modulation™ technology no longer just a vision, but reality.

Up to 1000x the sensitivity

All accelerometer designs are a compromise between frequency bandwidth and sensitivity. Good designs provide both a high bandwidth and at the same time a high sensitivity.

CEKO Sensors optical MEMS accelerometers have 10 times the sensitivity and 10 times the bandwidth compared to other frequency modulated optical sensors on the market. in a 100% metal-free design.



CEKO Sensors develop and manufacture advanced MEMS sensors in our state-of-the-art clean room facility. Extreme precision during patterning and etching as well as high quality materials with accurately controlled properties are some of the qualities necessary for building sensor components at the nanoscale.
