2.0 – 5.0 µm SPECTROMETER

Fiber coupled mid-infrared spectrometer
➢ Down to 5 cm-1 resolution
➢ Up to 130 kHz readout rate
➢ -80 dBm/nm sensitivity
➢ Full software included

7.6 – 12.0 µm PROTOTYPE SPECTROMETER

NLIR is expanding its technological framework into longer wavelength regions, currently 7.6 µm – 12.0 µm.

The spectrometer has free-space input and is therefore best utilized to analyze samples with a fixed, known light source like a conventional FTIR instrument.

The spectrometer is highly sensitive with typical exposure times of tens of milliseconds for an entire spectrum using a 30 W thermal lightsource. The resolution is 8 cm-1 – 10 cm-1. This spectrometer is optimal for at-line or in-line monitoring of, for example, liquid based samples in out-of-laboratory environments.

SINGLE-WAVELENGTH DETECTORS

Narrowband, highly sensitive point detectors
➢ From DC to > 10 GHz
➢ Amplified output in +/- 5 V range
➢ Extremely sensitive, down to few fW/sqrt(HZ)
➢ Fiber or free-space input
➢ Center wavelength in range 2.2 µm – 5.0 µm

NLIR Single-Wavelength Detectors

WAVELENGTH CONVERSION MODULE

Benefit from the core of the NLIR technology in your own setup. The conversion module converts mid-infrared light in the bandwidth 2.0 µm – 5.3 µm to the bandwidth 695 nm – 886 nm, where Silicon-based detectors are efficient.

The conversion module simplifies a wide range of mid-infrared light measurements by enabling conventional light analysis equipment. For example, connect the output fiber of the conversion module to a cheap and compact grating spectrometer that covers the needed bandwidth to gain spectral information about your mid-infrared light. Or connect the output fiber to your own point detector with ultra-high response or GHz bandwidth to perform measurements in the time domain.

THERMAL IR LIGHT SOURCE

Thermal light sources are stable and easy to work with. One problem that often arises, however, is to get the light to the sample and/or detector.

With NLIR’s fiber coupled IR light source it is easy to get the IR light right next to the sample. The light can easily be focused back into another fiber for detection.
