Fiber Optics Spectrometers

Optical spectroscopy is a technique for measuring light intensity in the UV-, VIS-, NIR- and IR-region. Spectroscopic measurements are being used in many different applications, such as color measurement, concentration determination of chemical components or electromagnetic radiation analysis. For more elaborate application information and setups, please click on the Applications link in upper the menu. We have defined different spectrometer lines to seperate our instruments:

AvaSpec StarLine

The AvaSpec StarLine family of instruments is compromised of high-performance spectrometers which exceed the demands of most general spectroscopy applications. The StarLine includes high-speed instruments for process control (AvaSpec-128 and AvaSpec-FAST-series), high-resolution instruments for demanding measurements like atomic emission (AvaSpec-ULS3648) and versatile instruments for common applications such as irradiance and absorbance chemistry (AvaSpec-ULS2048 & Avaspec-ULS2048L).

AvaSpec SensLine

The AvaSpec SensLine family of products is Avantes’ response to customers who require higher performance for demanding spectroscopy applications such as fluorescence, luminescence and Raman. The AvaSpec SensLine product line includes five high-sensitivity, low-noise spectrometers. Three of the instruments are based on back-thinned detector technology, of which two feature high-performance thermoelectrically cooled detectors.

AvaSpec NIRLine

The AvaSpec NIRLine instruments are high-performance, near-infrared spectrometers that are optimized for the demands of measuring long wavelengths. This line provides leading-edge performance for dispersive NIR instruments with toroidal focusing mirrors and dynamic dark correction for enhanced stability.

AvaSpec CompactLine

Miniature spectroscopy redefined. That's what we consider the CompactLine series spectrometers. 
The new generation AvaSpec-Mini is definitely one of the smallest spectrometers at the market today.


  • Reflection and transmission measurements for optics, coatings, color measurement
  • Irradiance and emission measurements for environmental, light characterization, and optical emission spectroscopy
  • High-speed measurements for process control, LIBS or laser/pulsed source characterization
  • Absorbance chemistry


The SensLine is all about sensitivity. For those measurements under hard conditions, low emissions: the SensLine gives you that extra power

  • High-stability
  • High-sensitivity
  • High-speed acquisition
  • Low-noise


An Ideal choice for OEM applications in which you require both compact size and high resolution with of course, an affordable price.
