Spectral Instrument System

Monochromators

Monochromators act as tunable bandpass filters for light. They are the critical component for many spectral applications since they can be used to create tunable light sources and also to take high precision spectral measurements.

The Digikröm line of Monochromators available in 1/8, 1/4 and 1/2 meter Focal Lengths use electronics that are 'designed-in', rather than appended via accessories or other add-ons after the instrument has been manufactured.

The Direct Digital Drive is simple and reliable; a microprocessor-controlled stepper motor, moving in wavelength increments as small as .01nm per step, is linked directly to the grating mount by a worm and worm wheel arrangement.

This results in improved accuracy, automatic grating changes and exceptional ruggedness.
