Spectral Engines

Spectral Engines is advancing material sensing technology with the NIRONE Sensor line, a series of Micro Electro Mechanical System (MEMS) Fabry-Perot Interferometers that can be used on its own or integrated in original equipment manufacturer (OEM) products.

NIRONE Sensor + CS&T Probe

Custom Sensors and Technology has incorporated the Spectral Engines NIRONE sensor into their CST 3323 Series Probe. This powerful duo combines the precision of the CS&T probe with one of the world’s most advanced MEMS IR spectrometer. Easily and precisely conduct NIR measurements of liquids and other samples on your work bench or out in the field.

The NIRONE Sensor in 3 different ways

  • NIRONE Sensor
  • NIRONE Device
  • NIRONE Scanner


The NIRONE Fabry-Perot spectrometer was fabricated using MEMS technology. This process results in the smallest NIR sensor available on the market today, with higher signal-to-noise than both traditional NIR spectrometers and competitive products using MEMS technology. NIRONE spectrometer modules are available from 1.35 – 2.45 microns (with a 1µm starting wavelength option available soon). Each individual spectrometer has a range of 350-500 nm, making these spectrometers the building blocks of a sensor system.

The Original Equipment Manufacturing (OEM) sensor is packaged with electronics and a variety of integrated collection optics options and is available in any quantity. With application development kits including a full stack of software tools for testing a new device concept, we can help you speed your way to a new product and market-entry of your unique material sensing solution significantly.

The NIRONE technology was the winner of the 2016 Photonics Prism Award.

Once the product is ready, the OEM sensors are available in batches of 10 or more.


NIRONE Device provides a more complete material sensing solution in an integrated package. The heart of the system is NIRONE Sensor with added mobility and connectivity.  The battery-powered NIRONE Device has Bluetooth connectivity enabling communication with portable devices such as mobile phones and tablets. The micro-USB connection is used for charging and communication with Sensor Control software.

NIRONE Scanner

NIRONE Scanner offers ready-made and modular building blocks to speed up market-entry for your unique solution. Proven technology and our committed development team will help you to pole position in the fast-growing material sensor market.  The NIRONE Scanner Platform includes:

  • Portable spectral scanners
  • NIRONE Scanner Mobile App
  • NIRONE Scanner Web App
  • Advanced cloud computing algorithms for material analysis
