Introducing the DM double monochromator series. Combining the dispersive powers of 2 coupled spectrographs allows for increased spectral resolution. Subtractive mode operation converts these instruments into ultra high performance, narrow bandpass filters with extremely high stray light suppression. Multiple entrance and exit ports for CCDs, PMT's and other detector types increase experimental usability and flexibility.
TriVista Overview
Work at Any Wavelength
TriVista operates at any wavelength from UV to IR and can work efficiently with multiple excitation wavelengths and tunable lasers. No edge or notch filters are needed for operation. In fact, TriVista’s performance is superior to common edge or notch filters having sharper and higher quality transmission edges, so you can observe spectral features closer to the instrument cut-off wavelength.
The TriVista can achieve higher resolution by combining the dispersion of all three spectrograph stages. This allows for the separation and resolve of any spectral features that are in very close wavelength vicinity.
High Spectral Resolution
Reveal more details in your spectra by combining the diffractive power of 2 or all 3 spectrograph stages. TriVista gives you up to 3x higher resolution compared to a single stage spectrometer. High resolution not only resolves more spectral features, but also allows you to track energy shifts and changes with much higher precision.
Measure Close to the Laser Line
Exceptional stray light rejection means that you can observe spectral lines much closer to the excitation laser energy. Detect small energy shifts and low frequency Raman spectra as close as 5 cm-1 (0.62meV) from the excitation laser using CCD detection, or 2 cm-1 (0.25meV) using single channel PMT or APD detectors.
