Abstract
An electronic testing device for pre-operative checks of medical scopes such as fluorescence imaging instruments. The testing device includes a light sensor configured to receive excitation light from an excitation light source and a light emitter configured to emit an emission light to be detected by a fluorescence imaging instrument. The testing device may include an optical light excitation filter, aligned with the light sensor, having a discrete excitation wavelength band corresponding to an excitation wavelength of a first fluorophore. The emission light emitted by the light emitter is of an excitation wavelength corresponding to an emission wavelength band of the first fluorophore.
