Princeton Instruments and Acton Research Corp. have created the TriVista triple Raman spectrometer with an optimal working range from 250 to 1050 nm and typical spectral resolution of <0.02 nm over the entire range, or 0.2 cm−1 at 500 nm. High stray-light rejection allows Raman spectra down to 5 cm−1 from the laser's Rayleigh line. Optionally, Stokes and anti-Stokes can be acquired at once. Multiple I/O options and scanning photon counting are supported. A sample chamber is available for solid and liquid samples. The multiple entrance option allows three sources to be connected simultaneously.
