Spectral Engines’ NIRONE® Sensor S uses patented Micro Electro Mechanical System (MEMS) Fabry-Perot Interferometer enabling fast and reliable measurements even in the most demanding environments. NIRONE Sensor S works at the true near infrared (NIR) spectral range from 1100 to 2450 nm which means better sensitivity and specificity in material sensing applications. NIRONE Sensor S offers excellent performance fully comparable to the best laboratory instruments in a small package and only a fraction of the cost.

The sensors are designed for system integrators for creating leading-edge products based on our smart NIR sensor platform. Compact sensors include two integrated light sources, NIR sensor, read-out and driving electronics and built-in intelligence, which guarantees extremely stable output even for the most demanding industrial or consumer applications. The spectral sensor can easily be adapted to your measurement needs with suitable front optics. A single electrical connector (I2C communication) makes the sensor easy to integrate into your own electronics, whenever needed.


NIRONE Sensor S Evaluation Kit provides a good starting point for technology evaluation and application studies. The evaluation kit includes a USB communication board and the sensor can be controlled via PC by using our user-friendly SensorControl software. The evaluation kit is by far the easiest and fastest way to start your NIR applicatiosn studies right away. Our SensorControl software is free to use with any of our devices.
