PoliSpectra - Model M116 -MultiTrack Spectrometer

The PoliSpectra® MultiTrack systems feature high throughput/ sensitivity and a 2D Scientific back-illuminated CMOS sensor which can be configured with 8,16 or 32 fiber input channels for simultaneous acquisition of UV-NIR spectra.

With an optional nitrogen purge, the system can be configured for low UV coverage. Additionally the high QE sCMOS sensor and an integrated order sorting filter allow wavelength coverage beyond 1 μm.
