Removal of specific wavelengths or wavebands from beam of laser-scanning-microscope is accomplished by prism-dispersion and selective, physical blanking

摘要

The beam is split up using a dispersive element, e.g. a prism (P), and proceeds to meet a concave mirror (HS). Ahead of the mirror, there is an adjustable unit blanking off individual wavelengths or wavebands of the incident and/or reflected beams.
