Hamamatsu Photonics has launched the Chromatiq Spectral Engine (CSE) made by its subsidiary Energetiq Technology.

This pioneering light source manufacturer designed a breakthrough product now featuring an extension to near-infrared (NIR) wavelengths.

The CSE, initially introduced in 2021 and recognised with the esteemed Laser Focus World Innovator’s Award, addresses a crucial challenge faced in light sensing and colour measurement applications: the ability to generate light with highly specific spectral content, emulating real-world lighting conditions and other custom spectra to meet calibration and testing requirements.

What sets the CSE apart from existing solutions in the market is its high spectral resolution enabled by Energetiq’s Laser-Driven Light Source (LDLS) technology. LDLS, a plasma-based broadband light source, is recognised for its outstanding spectral radiance, stability, long lifetime, and broad wavelength range.

The CSE not only outperforms comparable sources in terms of resolution, but it also boasts a lightning-fast switching speed of <10 ms between programmed spectra. The added NIR wavelength range covers the full active range of silicon-based detectors, from 380 nm to 1,100 nm, offering precise alignment between light source and detector.

Key features and functionalities that define the uniqueness of the CSE include:

  • Realistic spectrum matching: Ensures accurate simulation of real-world lighting conditions.
  • Laser-driven light source technology: Built on LDLS technology for unmatched performance.
  • Custom spectrum generation: Offers multi-peak, flat top, ramp top, and narrow peaks as well as dimming capabilities.
  • Production-optimised switching speed: Facilitates fast switching for efficiency in production environments.

The CSE caters to a broad audience, including manufacturers of colour sensors, spectrometers, and image sensors, as well as anyone integrating these optical sensing technologies into finished products. The applications span a diverse range, from consumer electronics and advanced driver assistance systems to evolving needs in the aerospace industry.

“Customers can expect improved levels of reliability and efficiency from seamlessly integrating the CSE into multiple stages of their production processes,” said Debbie Gustafson, CEO of Energetiq.

“The CSE provides the accurate and repeatable data necessary to support cutting-edge product innovation across multiple industries.”
