Multi-Channel CCD Spectrometers

Multi-Channel CCD Spectrometers Description：

Datasheet

Multi-channel spectrometers are used to monitor or measure multiple samples or sources simultaneously. Traditionally, multi-channel imaging spectrometers have been expensive and bulky instruments used only in demanding laboratory and industrial applications. Mightex has leveraged the state-of-the-art optics and CCD cameras to bring to the market a compact and low-cost multi-channel fiber spectrometer that features high spectral resolution and high light throughput.

At the heart of Mightex multi-channel spectrometers is a high-throughput flat-field imaging spectrograph. Multiple input fibers, each represents an independent signal channel, are aligned along the input slit of the imaging spectrograph. Spectrum of each channel is dispersed by a high-efficiency diffraction grating and then imaged on to 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 ½“ 1.3MP Sony ICX205 imager with a 12-bit ADC. Exposure time (integrating time) can be varied between 50μs and 200s. The electronics hardware also includes trigger input and four programmable digital I/Os for interfacing with other equipment such as a light source. The spectrometer is controlled through a USB2.0 interface which also supplies all the electric power needed to operate the spectrometer. Mightex also integrates other cameras to build custom multi-channel spectrometers.

Input ends of the fibers are connectorized with SMA905 connectors. Sleeves are available to connect the fibers to other SMA connectors. Standard software package includes a full-featured multi-channel spectrometer PC software as well as a software development kit (SDK) for further software development. The software also supports radiometric calibration and photometric calculations.
