Choosing the Right Monochromator

Choosing the right monochromator depends on the careful consideration of several factors. Here are some of the most important ones.

#1 Application
A given scientific, academic, or engineering process that requires scans of wavelength intervals is better served by scanning monochromators, due to the motor controls inherent in these models.

#2 Environmental Risk
Physical damage to monochromators is possible, particularly in motor-driven models that operate over broad wavelength spectrums. The screw or pin mechanism can damage the internal grating or mirrors if it is pushed beyond its wavelength limits. To mitigate this risk, our scanning monochromators are equipped with dual photosensors that serve as limit switches to prevent such damage.

#3 Wavelength Range
A monochromator will not do you any good if it cannot isolate light according to the wavelength specifications unique to your application. So choose the one that’s best suited for your range of wavelengths.
