Theoretical background: Spectrometers
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). This instrument line offers an array of solutions for varied uses, while providing excellent price-to-performance ratios.
The AvaSpec-ULS2048/2048L and AvaSpec-3648 are based on front illuminated linear CCD arrays and thanks to Avantes’ DUV coating can measure wavelengths from 200-1100 nm. The AvaSpec-FAST series of instruments is specially designed for high-speed acquisitions such as pulsed light source and laser measurements. The AvaSpec-128 is an ultrafast photo-diode array-based instrument for visible and near-infrared applications.
Instruments in the AvaSpec StarLine family are designed to perform in a variety of applications such as:
- 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
AvaSpec StarLine instruments are fully integrated with Avantes’ modular platform, allowing them to function stand-alone, or as multi-channel instruments. These products are fully compatible with other AvaSpec instruments in our AvaSpec SensLine and NIRLine. The entire AvaSpec StarLine is available as an individual lab instrument or an OEM module for integration into a customers’ existing system.
The StarLine instruments are available with our standard AvaBench-45 optical bench (45 mm focal length) or the Ultra-Low Stray-light (ULS) optical bench (75 mm focal length). The AvaSpec StarLine instruments are also available with a number of premium options such as irradiance/intensity calibration and non-linearity calibration.
The AvaSpec SensLine family of products is Avantes’ response to customers who require higher performance for deman-ding 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. The other two models are based on standard CCDs, upgraded to high-performing instruments as a result of Avantes’ unique and recently improved detector cooling technology. The back-thinned CCD detectors featured in the AvaSpec SensLine product family are high quantum efficiency detectors with excellent response in the UV, VIS and NIR from 200-1160 nm.

These products are fully compatible with other AvaSpec instruments in our AvaSpec StarLine and AvaSpec NIRLine product families. The entire AvaSpec SensLine is available as a lab instrument or an OEM module for integration into a customers’ existing system.Avantes’ innovative ultra-low stray-light (ULS) and revolutionary new High-Sensitivity (HS) optical benches are the core optical technologies in the AvaSpec SensLine. These highly stable optical benches combined with our high-performance AS5216-USB2 electronics board deliver high-performance instruments at affordable prices.
All members of the AvaSpec SensLine are designed to provide performance features such as:
- High-speed acquisition
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. The NIRLine is comprised of both thermo-electrically cooled and un-cooled instruments. AvaSpec-NIR256-1.7 features an uncooled 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.
AvaSpec NIRLine instruments are fully compatible with our AvaSpec StarLine and SensLine spectrometers. Avantes’ AvaSpec NIRLine instruments are available as laboratory instruments or OEM modules. AvaSpec NIRLine instruments are available with a number of premium options such as irradiance/intensity calibration and non-linearity calibration.
The AvaSpec NIRLine of 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 feed and food
