Measurement of different fluorescence spectra on object in case of age-related degeneration of lens with cataract by exciting object region for fluorescence and their confocal imaging on inlet slit of spectrograph

摘要

An object is illuminated for a fluorescence excitation simultaneously with spatially separated and chromatically different excitation rays. The object region/ranges excited for the fluorescence are confocally imaged on an inlet slit of a spectrograph. The fluorescence spectra obtained from the same detector system are then registered. A field aperture (12) is formed as slit-shaped and confocal to entry slit (25) and the separating location between the different-wavelength filter ranges (14,15) of excitation filter (13) is made as light impermeable. An Independent claim is included for: (a) a device for measuring of different fluorescence spectra of an object
