Multichannel Spectrometers

Multichannel spectrometers are used to monitor or measure multiple samples or sources simultaneously. Mightex Systems has combined advanced optical and CCD camera technology to create compact multichannel fiber spectrometers that feature high spectral resolution and high light throughput. At the spectrometers’ core is a flat-field imaging spectrograph. Multiple input fibers, each representing an independent signal channel, are aligned along the input slit of the imaging spectrograph. Spectra of each channel are dispersed by a diffraction grating and then imaged onto a 2-D CCD sensor, with light from each channel occupying different rows on the sensor. All channels are exposed simultaneously, then rows associated with each are binned together to produce a spectrum for the channel. Fiber channels are spaced to eliminate crosstalk between adjacent channels.

GLOSSARY
analog-to-digital converter
A device that converts an analog signal, that is, a signal in the form of a continuously variable voltage or current, to a digital signal in the form of bits.
diffraction grating
A glass substrate carrying a layer of deposited aluminum that has been pressure-ruled with a large number of fine equidistant grooves, using a diamond edge as a tool. Light falling on such a grating is dispersed into a series of spectra on both sides of the incident beam, the angular dispersion being inversely proportional to the line spacing. By proper shaping of the diamond edge, however, the grooves can be formed in such a way as to concentrate most of the energy into a single spectral...
spectrograph
An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
