Source of light for illumination in a scan microscope has an electromagnetic source of power emitting light for a wavelength while upstream to a device for apportioning light into two dividing beams of light.

摘要

An electromagnetic source of power (3) emits light (17) for a wavelength and is upstream to a device (5) for apportioning light into two dividing beams of light. There is an intermediate element (9) in the first dividing beam of light (21) to alter wavelengths. The second dividing beam of light (19) is aligned directly onto a specimen (41) to give optical stimulation to a first area. An Independent claim is also included for a scan microscope with a microscope lens, a detector and a beam deflector device for guiding an illuminating light beam over a specimen.
