Product Details

Mid-infrared (MIR) spectroscopy is used to analyze MIR light sources and, in both industry and research, for non-invasive characterization of gases, liquids, and solids as well as characterization of light sources. The NLIR 2.0 – 5.0 µm Spectrometer (S2050-400/S2050-130k) is based on a novel measurement scheme that upconverts the MIR light to near-visible light. Silicon-based near-visible light detectors are far superior to MIR light detectors in terms of detectivity, speed, and noise. The NLIR upconversion technology, therefore, brings these attractive features and the advantages that follow, to the MIR regime.

Both editions seen below have sensitivities at -80 dBm/nm or better, and the maximum full-spectrum readout rate is 130 kHz! As a result, the spectrometer enables the characterization of light sources and measuring spectral content from chemical processes with a time resolution of less than 10 µs.

Spectrometer Measurements Examples

S2050-130k spectrometer measurements

40 kHz Single Pulse Measurement

Single pulses from a super-continuum light source with a bandwidth of approx. 3.5 µm – 4.2 µm and a repetition rate of 40 kHz of 2 ns pulses were measured with 80 kHz full-spectrum readout rate. In the figure, (a) shows raw data of 12 ms data acquisition, (b) shows a zoom where every other readout is empty as expected from 40 kHz rep-rate and 80 kHz sampling, (c) shows 10 raw consecutive spectra. The fluctuations in the spectra is by far dominated by noise from the light source.

Based on this measurement, the S2050-130k spectrometer is capable of characterizing fast modulations of infrared lasers and other dynamic events. 

Plastic Transmission

A 30 W globar was used as the light source for these transmission measurements of a 50 µm polystyrene (PS) film and a 800 µm polyethylene terephthalate (PET) film. The S2050-400 spectrometer was set to 20 ms exposure time and capturing just single shots. No averaging or smoothing has been applied to the data subsequently.

Computer algorithms can certainly tolerate a much shorter exposure time, and thus a faster acquisition, in the context of plastic recognition or thickness analysis.

Optical Coating Transmission

A 30 W globar was used as the light source for these transmission measurements of coated optical windows: a Ge bandpass filter (BPF) for 3.7 – 4.5 µm and a YAG mirror coated with high reflection at 1064 nm and high transmission at 2.1 -4.5 µm. The S2050-400 spectrometer was set to 20 ms exposure time and captured just single shots. No averaging or smoothing has been applied to the data subsequently.

Coating quality control or production monitoring may require such measurements.

Fiber Reflection Probe

fiber reflection probe is a single-bounce attenuated total reflection (ATR) crystal that has fiber-coupled input and output. In this measurement, light from a 30W globar was coupled to the input fiber, and the output fiber was connected to the S2050-400 spectrometer. By first taking a reference with the ATR probe in air, the probe was subsequently inserted into water, propane-2-ol, and sunflower oil, respectively, producing these absorption plots. The measurements were single-shot at an exposure time of 100 ms, and a 4-pixel wide Gauss filter was scanned through the data for smoothing.
