Raman Spectrometers for Excitation, Detection and Analysis

Using Raman spectroscopy, individual spectral 'fingerprints' materials can be obtained. This type of spectroscopy is generally used in medical, pharmaceutical, and chemistry domains to offer data through which molecules can be detected.

To provide its customers with optimal performance at an affordable price, Avantes has collaborated with two different partners to provide three simple Raman bundles, which comprise a unique laser-probe combination (785 nm) that supplies improved signals, a high-performing spectrometer (three different versions) and an exceptional software package to study the Raman spectra.

Type of Measurements

The Raman technique is applied to several different materials. The Avantes bundles are exceptionally good for the use of liquids and powders. For extremely weak signals and possibly along with fluorescence background, the AvaRaman-D (Highsense Bundle) using Avantes’ AvaSpec-HERO is suggested (improved signal-to-noise performance and higher quantum efficiency in NIR).

The thermo-electric-cooled (TEC) spectrometer is suggested in case weak Raman signals occur (longer than 5 seconds of integration time). This spectrometer is added in the AvaRaman-E (Performance Bundle). When there are powerful signals (alcohol-based liquids and aromatic compounds), the AvaRaman-F (Basic Bundle) is handy to carry out the measurement.

Application Fields

  • Semiconductors
  • Raw materials identification
  • Mineralogy and gemology
  • Pharmaceuticals and medical diagnostics

Types of Bundles

Three different bundles are available, and each setup includes a specialized spectrometer to suit the application needs of users. The three bundles share the following features.

For Excitation

AvaLaser785 (including 785-nm laser safety goggles) has an ultra-high throughput integrated Raman probe. This innovative device features a built-in wavelength stabilized laser source along with beam shaping optics, Raman filter packs and high-efficiency Raman spectra collection optics.


  • High-throughput optical design with 100 cm−1 cut-on
  • A 785-nm wavelength stabilized excitation source
  • External control box to adjust the power (software/manually controlled)

For Analysis

The AvaSoft-Raman: This is a basic standalone software that helps acquire spectra.

Panorama-Light: This is a high-end, modular software platform meant for assessing spectroscopic data. The application fulfills all the needs for an in-depth spectroscopy working environment, and enables:

  • Measurement through an instrument
  • Two-dimensional and three-dimensional data visualization
  • Searching in libraries
  • Printing with professional print templates
  • Archiving in spectral libraries, such as additional data
  • Sharing information with office applications, the Panorama Light can perfectly support users and keep them focused on their routine work
  • Converting several familiar data formats

For Detection

Avantes provides next-generation spectrometers based on the Avantes StarLine and SensLine spectrometers, customized for optimal performance in the targeted Raman range.
