At the heart of Mightex (Pleasonton, CA) multi-channel spectrometers is a high-throughput flat-field imaging spectrograph. Multiple input fibers, each representing an independent signal channel, are aligned along the input slit of the imaging spectrograph. The spectrum of each channel is dispersed by a high-efficiency diffraction grating and then imaged onto a 2D CCD sensor. Light from each channel occupies different rows on the CCD sensor. All channels are exposed simultaneously, then rows associated with each channel are binned together to produce a spectrum for the channel. Fiber channels are spaced out properly to essentially eliminate crosstalk between adjacent channels. The standard CCD camera features a 1/2" 1.3MP Sony ICX205 imager with a 12-bit ADC. Exposure time (integrating time) can be varied between 50us and 200s.
