Context:
Mid-infrared wavelengths contain rich chemical information but require specialized and expensive detectors to measure directly. Traditional MIR detectors can be slow, costly, and less sensitive than visible-range alternatives.
Solution Intro:
The NLIR SPEKTRUM Wavelength Converter translates broad-range MIR wavelengths into the visible/NIR spectrum, enabling detection using common Si or GaAs sensors found in Avantes spectrometers — no specialized MIR detector needed.
Step-by-Step Visual:
MIR Source: Light from your MIR measurement setup enters SPEKTRUM (1.9–5.3 µm). NLIR
Broadband Conversion: SPEKTRUM upconverts all wavelengths in this range at once to 682–886 nm with no scanning parts required. NLIR
Avantes Detection: The converted light is fed into an Avantes VIS/NIR spectrometer via fiber, where familiar software captures and analyzes the data.
✔ Extend Existing Spectrometers:
Read MIR signals using your Avantes VIS/NIR systems — no need to invest in separate MIR detectors. NLIR
✔ Broadband, Instant Conversion:
SPEKTRUM converts the entire 1.9–5.3 µm range simultaneously into 682–886 nm without scanning, enabling real-time measurement workflows. NLIR
✔ High Speed & Real-Time Capable:
Unlike many traditional MIR systems, conversion output can be analyzed at VIS/NIR detector speeds, ideal for dynamic process monitoring. NLIR
✔ No Alignment or Tuning Needed:
The integrated converter requires no optical alignment — just fiber-in, fiber-out connectivity.
