Two excitation wavelength video imaging microscope

摘要

An imaging apparatus which includes: a fluorescent imaging microscope; a uv radiation source capable of producing a plurality of uv excitation wavelengths; a filter device to select a first and a second excitation wavelength from the plurality of uv excitation wavelengths; a sample chamber to hold a sample for illumination by the radiation of the first and second wavelengths; a photometer to measure the intensity of the excitation wavelength being selected by the filter device and to generate an intensity signal representative of the measured intensity; and a processor in communication with the photometer to record the intensity signal produced by the photometer.
