Multispectra, Multifiber, Multichannel Imaging spectrometer with 8-16-32 Simultaneous UV-NIR Spectra
HORIBA designs and manufactures a large range of custom OEM fiber-coupled, multi-spectra spectrometers capable of simultaneous measurement of up to 32 fiber channels and sequential measurement up to 96. Utilizing a concentric imaging spectrometer with a broadband spectral range and a customized fiber bundle, the HORIBA OEM multifiber spectrometers provide excellent imaging quality with minimum crosstalk.
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.
