Description of technology
miniRaman spectrometer is an advanced miniaturized Raman spectrometer with clear aperture on optical elements of 4 mm. The total dimensions of the miniRaman spectrometer module are 25 x 30 x 105 mm including two lasers, laser beam delivery optics, set of sample probes, Raman beam delivery optics, electronics, battery and housing.
lasers at the wavelength: 660 nm and 785 nm
laser power can vary between 2-30 mW at 660 nm, 15 to 150 mW at 785 nm
spectral range 2750-4500 cm-1 at 660 nm, 400-2500 cm-1 at 785 nm
spectral resolution 10-15 cm-1 (depending on a spectral range)
wavenumber accuracy ±2.5 cm-1
In order to obtain an automatic calibration of the unstabilized laser wavelength drift, Lightnovo ApS implemented a unique (patented) reference channel in our spectrometer. Therefore, the miniRaman measurements are calibrated after each new spectrum. MiniRaman has an extremely high total Raman signal throughput from sample to detector (~89%).
The device has the following output specification:
