Meet the Chromation Spec, a new generation of compact spectrometer

  • The Chromation Spec is a compact, low-cost, easier to use alternative to traditional grating spectrometers.
  • The current generation offers broadband UV/VIS/NIR response (~275-1050nm) with 15nm FWHM 
  • Our roadmap includes a chip version to address the growing demand from mobile/wearable/disposable applications and extension to longer wavelengths.

Two key innovations

A folded optical path with integrated apertures, mirrors, and absorbers structure incident light.
Photonic crystal scattering creates broadband spectral selectivity in a small volume.

The combination of these two key innovations create an easy to manufacture element that contains all of the optical functionality for a spectrometer. These dies are fabricated at the wafer scale using scalable processes, and have a simple stacked alignment to the detector.

Overview

Chromation has created the world's first commercial photonic crystal spectrometer. The technology provides best-in-class spectral range with competitive spectral resolution in an highly compact form factor. The optical component is manufactured using a scalable silicon-compatible process for a low component cost, and the designs scales down to chip scale. The Chromation Spec is the first product using this technology. It delivers new capabilities for integrated applications and can be deployed into distributed sensor networks.
Value in Applications
  • Broad spectral range for measurement of visible and NIR signatures, indicators, and markers
  • Versatile light sensor for visual and non-visual applications such as color rendering index, melanopic response, and PAR
  • Suitable for UV applications and detection of fluorescence
  • Low cost enables arrayed mesh sensor networks and other distributed applications
Sensor Attributes
  • Broad spectral range allows a single platform to perform diverse tests
  • Small, light, no moving parts
  • Point and shoot - no external optics required
  • Revolutionary range, cost, and size advantages offer new integration opportunities for spectral measurement
