Combine Avantes VIS/NIR spectrometers with the NLIR SPEKTRUM Wavelength Converter to transform mid-IR signals (1.9–5.3 µm) into the visible range, enabling the Avantes NEXOS to capture rich molecular information with speed, sensitivity, and simplicity.
Mid-infrared wavelengths contain rich chemical information but require specialized and expensive detectors (FTIR, HgCdTe) to measure directly. Traditional MIR detectors can be slow, costly, and even less sensitive than visible-range alternatives.
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.
MIR Source: Light from your MIR measurement setup enters SPEKTRUM (1.9–5.3 µm).
Broadband Conversion: SPEKTRUM upconverts all wavelengths in this range at once to 682–886 nm with no scanning parts required.
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.
✔ 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.
✔ 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.
✔ No Alignment or Tuning Needed:
The integrated converter requires no optical alignment — just fiber-in, fiber-out connectivity.
NLIR’s wavelength conversion module upconverts mid-infrared light to the near-visible range using a high-power 1064 nm laser in a lithium niobate crystal, enabling detection with standard Si and GaAs detectors—no alignment required. The SPEKTRUM Wavelength Converter simultaneously converts 1.9–5.3 µm to 682–886 nm without scanning, allowing analysis with conventional fiber-coupled spectrometers or silicon-based detectors.
