Mightex has developed a compact and low-cost multi-channel spectrometer with high spectral resolution and high throughput.
At the heart of the spectrometer is a flat-field imaging spectrograph. Multiple input fibres, each representing an independent channel, are aligned along the input slit of the spectrograph. Spectrum of each channel is dispersed by a diffraction grating and then imaged onto a 2D CCD sensor, and light from each channel occupies different rows on the sensor. The rows associated with each channel are binned together to produce a spectrum. The multi-channel spectrometer has a USB 2.0 interface, which also powers the spectrometer so there is no need for an external power supply.
