NIRLine Spectrometers

For measurements in the NIR region from 900 to 2500nm, Avantes has developed a family of  Near Infra-red spectrometers called NIRLine.


The line up starts with the very affordable AvaSpec-NIR256-1.7, which is also available with replaceable slit, and progresses to include the most sensitive, cooled near infrared spectrometers on the market today, offering coverage up to 2500nm.

The NIRLine is comprised of both thermo-electrically cooled and non-cooled instruments. AvaSpec-NIR256-1.7 features a  non-cooled 256 pixel InGaAs detector.  All other instruments in the NIRLine have thermo-electric, peltier-cooled InGaAs detectors which support cooling down to -25°C against ambient.


All NIRLine instruments are fully compatible with our AvaSpec StarLine and SensLine spectrometers, and are available as laboratory instruments or OEM modules. NIRLine instruments are available with a number of premium options such as irradiance/intensity calibrations, and non-linearity calibrations.The AvaSpec NIRLine instruments are designed to perform in a variety of applications such as...

  • Moisture content measurement of liquids, solids and powders for inline and quality control purposes

  • Quantitative and qualitative measurement of volatile organics such as ethanol, and methanol

  • Plastic characterization and material identification

  • Irradiance measurements, such as solar monitoring

  • Qualitative measurements of feeds and foods


Selected models feature a High Sensitivity/Low Noise setting, which enables an easy choice between the highest possible sensitivity and the lowest possible noise, right from within AvaSoft 8.

What is spectroscopy, and what is a fibre optic spectrometer?

Optical spectroscopy is a technique for measuring light intensity in the UV, VIS, NIR and IR region, and a spectrometer is typically the device used to do this. Spectroscopic measurements are being used in many different applications, such as colour measurement, concentration determination of chemical components or electromagnetic radiation analysis to name just a few. Traditionally, it was typically necessary to take a sample of what ever medium you wanted to measure and measure it with a spectrometer in the lab. These days, progress in optical fibre technologies has revolutonised the spectroscopy business, and their use allow us to go right to the object being measured. Devices that make use of this technology are correctly classed as spectrometers, but more specifically, they're fibre optic spectrometers. Using this technique enables a truly unlimited number of applications in both the lab and field, with new applications being discovered everyday.
