Monochromator
300-700 nm | MonoScan2000
Ocean Optics
The MonoScan2000 is a computer-controlled scanning monochromator with a 300-700 nm wavelength range. It takes the MonoScan2000 only three seconds to scan from 300-700 nm. To scan only one nanometer takes about 15-20 milliseconds. The MonoScan2000 is compatible with all Ocean Optics spectrometers, light sources, accessories and optical fibers.
Use as a Tunable Light Source or Excitation for Fluorescence
In this setup, a broadband light source provides light via optical fiber to the MonoScan2000. You select a 2-to-3 nm bandpass in which the light passes before exiting the MonoScan, interacting with a sample and passing to a spectrometer. In this situation, the MonoScan takes the place of a filter. A scanning monochromator is better able to provide excitation intensity than a filter because of the monochromator's ability to reject out-of-band illumination. Filters can provide adequate excitation intensity but at reduced optical transmittance because they typically have a wider bandpass. You often sacrifice dynamic range with filters.
