Provided is an imaging optical system that can prevent enlargement of the entire optical system of a microscope apparatus while holding a wide distance between optical axes to allow enlargement to a low-power range. A variable power optical system 3 used in a parallel stereoscopic microscope apparatus 100 and the like includes a plurality of optical paths in which optical axes are arranged substantially parallel, includes a plurality of lens groups that change the magnification of a diameter of a luminous flux entering substantially parallel to each of the optical paths to eject the luminous flux as substantially parallel luminous fluxes, and at least two lens groups move along the optical axis in each optical path according to the change in the magnification. At least two lens groups of at least one optical path among the plurality of optical paths move in a direction including a component perpendicular to the optical axis according to the change in the magnification at at least part of a section where the magnification is changed from a high-power end state to a low-power end state.

A microscopy imaging system is disclosed that includes a light source system, a spectral shaper, a modulator system, an optics system, an optical detector and a processor. The light source system is for providing a first train of pulses and a second train of pulses. The spectral shaper is for spectrally modifying an optical property of at least some frequency components of the broadband range of frequency components such that the broadband range of frequency components is shaped producing a shaped first train of pulses to specifically probe a spectral feature of interest from a sample, and to reduce information from features that are not of interest from the sample. The modulator system is for modulating a property of at least one of the shaped first train of pulses and the second train of pulses at a modulation frequency. The optical detector is for detecting an integrated intensity of substantially all optical frequency components of a train of pulses of interest transmitted or reflected through the common focal volume. The processor is for detecting a modulation at the modulation frequency of the integrated intensity of substantially all of the optical frequency components of the train of pulses of interest due to the non-lincar interaction of the shaped first train of pulses with the second train of pulses as modulated in the common focal volume, and for providing an output signal for a pixel of an image for the microscopy imaging system.

摘要:
Die Erfindung betrifft ein Operationsmikroskop (100) mit einer Beleuchtungseinrichtung (110). Die Beleuchtungseinrichtung (110) kann mit einem ersten Beleuchtungsstrahlengang (111) und mit einem zweiten Beleuchtungsstrahlengang (112) Beleuchtungslicht zum Objektbereich (105) führen. In dem ersten Beleuchtungsstrahlengang (111) ist eine Lichtaustrittseinheit vorgesehen. In dem zweiten Beleuchtungsstrahlengang ist eine Leuchtfeldblende angeordnet. Der erste Beleuchtungsstrahlengang (111) weist eine Beleuchtungsoptik auf, welche die Lichtaustritts-Ebene der Lichtaustrittseinheit oder eine zur Lichtaustrittsebene konjugierte Ebene in eine erste Bildebene (350) abbildet. Erfindungsgemäß ist in dem zweiten Beleuchtungsstrahlengang (112) eine Beleuchtungsoptik vorgesehen, welche die Leuchtfeldblende in eine zweite, von der ersten Bildebene verschiedene zweite Bildebene (250) abbildet.
