Monochromators & Spectrographs


Monochromators are optical subassemblies that uses polychromatic input light from a source and outputs monochromatic light. The entrance ports, consisting of either slits or optical fibers are geometrically fixed. Inside the monochromator, there is a diffraction grating that is rotated and acts as bandpass filters such that high precision spectral measurements can be taken. The grating can be rotated manually or by motor.

Filter Wheels & Accessories

The filters, which are used to attenuate the light intensity and prevent unwanted spectral wavelengths from contaminating the recorded image, are merged with wheels to position selected filters in the imaging path quickly and accurately. Accessories complement the monochromators and spectrographs and are avaliable as spheres, fibers, probes and adapters.
