Abstract:
A geometrical beam splitter for transversally dividing a radiation beam into at least one reflected beam portion and at least one passing beam portion, said beam splitter:being composed of a piece of rigid material having a non-transparent reflective surface at an angle in respect to the incident direction of said radiation beam, said angle substantially deviating from the right angle; and having a width and a height extending over a total effective cross-sectional area of the radiation beam, and at least two holes extending through said piece of rigid material, wherein said holes have at least a length that is equal with the diameter of the holes and reflective walls to form radiation guiding wavetubes, whereupon: said holes allow passing of at least two beam portions with radiation from a substantially same object area or volume into separate and independent targets; and simultaneously said non-transparent reflective surface divert at least one reflected beam portion with radiation from said substantially same object area or volume into one or more separate and independent target(s), said beam portions having substantially similar wavelength distributions.
