World leading low-cost, high-performance spectroscopic systems   

Monochromators   

After introducing the first total microprocessor-controlled, direct drive scanning monochromator in 1987, Spectral Products' Digikröm line of monochromators is the culmination of over 25 years of experience in building instruments that combine microelectronics with precision optics. They feature computer control, direct digital drive, automatic grating changes and motorised slits, offering world leading low-cost, high-performance spectroscopic systems.
 
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 ⅛, ¼ and ½ metre 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 0.01 nm per step, is linked directly to the grating mount resulting in improved accuracy, automatic grating changes and exceptional ruggedness.
