Multichannel Grating Spectrometer

Horiba’s OEM Polispectra Quad spectrometer is an integration of four VS70 spectrometers built around Horiba JY Type-IV flat-field aberration-corrected holographic concave gratings. This high throughput VIS spectrometer with 4 fiber inputs provides simultaneous acquisition of 4 channels at high speed with minimal crosstalk. The main electronics board is designed to read the two CCDs on the system simultaneously and provides 1-8X binning capability. This OEM system is a unique and innovative approach to drastically reduce the cost per channel.
