Abstract:
1. An optical system for use in microscopy comprising: a laser configured to generate light having a wavelength range; imaging optics configured to image light generated by the laser onto an image plane; an optical component positioned between the laser and the imaging optics, wherein the light generated by the laser passes through the optical component, and wherein the optical component is configured to increase said wavelength range of said light to a substantial portion of the entire visible wavelength range; an attenuator for attenuating at least a portion of at least one wavelength of light emerging from the optical component, and wherein the attenuator comprises at least one of a spectrally selective filter, an acoustooptical tuneable filter (AOTF), an acoustooptical deflector (AOD) and an LCD, and wherein the laser comprises a pulsed laser; and a control loop for light output stabilization, which measures the light output in the beam path of the imaging optics and which maintains a constant specimen illumination light output by varying pumping light output of the pulsed laser or with the aid of an acoustooptical or electrooptical element.
