miniRaman spectrometer

The 3rd generation of the miniRaman spectrometer is the most compact and powerful version of the miniRaman series of Lightnovo. As the world’s smallest Raman spectrometer at all, it operates on a level of a research instrument and delivers excellent results for quantitative analyses with high sensitivity.

The special feature of the miniRaman spectrometer is an implemented reference channel (patented) which ensures that the spectra obtained are corrected compared to the reference channel spectrum. As a result the device is constantly calibrated and delivers fast and reliable results. By calibrating the spectrometer during each measurement, Raman shift and Raman intensity is automatically corrected.

Configurations

The miniRaman spectrometer is available with a 785 nm or 660 nm laser and can be configured individually.

For SERS measurements (surface enhanced Raman spectroscopy), the miniRaman 785 nm is available as SERS-configuration, which means lower performance on the sample. In case the spectral range from 270 – 3000 cm^-1 is too low (miniRaman 785 nm), the miniRaman 660 nm FULL RANGE with a spectral range of 270 – 3900 cm^-1 is suitable.

Features

With its compact size of 10,5 cm x 5 cm x 4,5 cm and a low weight of only 360 g the miniRaman spectrometer is ideal for portable applications. The integrated battery allows measurements of up to 4 hours. For in-field measurements the miniRaman can be equipped with a IP67 certification.

One-button operation allows comfortable and user-friendly measurements. The integrated display delivers immediate visualization of the Raman spectrum. When using databases (self-created or acquired) the unknown substances are identified instantly and displayed (if required with CAS number). A selection of the available spectral databases ranges from toxic to biomedical chemicals, food additives, semiconductors, petrochemistry and microplastics.

The miniRaman spectrometer can be controlled with an app for Android mobile devices via bluetooth or USB conncetion to the PC (Windows 10 and 11)
In addition to operating the device and recording and storing the Raman spectra, the Miraspec software allows

• data acquisition (laser power control, exposure time, sensor amplification, number of repetitions and spectral range)
• data pre-processing (baseline correction, spectral equalization and spectrum standardization)
• qualitative and quantitative analysis (PCA – principal component analysis, identification of materials, creation of spectral libraries, principal component regression, calibration of peak heights and areas)
