OPTICAL SYSTEM FOR MAPPING SIGNAL LIGHT ONTO A DETECTOR |
摘要 |
The invention relates to an optical system that particularly allows an improved detection of signal light propagating from a light source (1) through a flat glass substrate (11). SC-modes of this signal light that would normally be totally internally reflected at the backside (10) of the substrate (11) are coupled out by a first diffractive optical element DOE (21). To map all signal light leaving the substrate (11) onto a single target location (51), a focusing lens (31) and a second DOE (41) are disposed in the optical path behind the substrate (11). The DOEs (21, 41) may for example be a ID sinusoidal grating or a 2D blaze grating. The optical system may particularly be applied in an investigation apparatus for detecting multiple spots of a fluorescent sample material.
