    Abstract: Provided is a detection optical system that is provided with a dispersed-light detection function and that can increase the amount of detected light by enhancing the diffraction efficiency. A detection optical system 10 is employed which includes a transmissive VPH diffraction grating 11 that disperses fluorescence from a specimen into a plurality of wavelength bands; a rotating mechanism that rotates the VPH diffraction grating 11 about an axial line L that is perpendicular to an incident optical axis of the fluorescence from the specimen and an emission optical axis from the VPH diffraction grating 11; a light detection portion 15 that detects the fluorescence from the specimen that has been dispersed by the VPH diffraction grating 11; and a correcting portion that corrects an incident position on the light detection portion 15 in accordance with a displacement of the optical axis caused by the rotation of the VPH diffraction grating 11 in synchronization with the rotating mechanism.

    Abstract: Disclosed is a spectroscopic device that includes a light input unit to which light from a light source is input; optical elements; an optical deflection element; a reflector element that reflects the light emitted from the optical deflection element; and a photodetector. The optical deflection element includes a refractive index change region made of a material having an electro-optical effect and electrodes arranged to pinch the refractive index change region. The reflector element is a resonator filter having wavelength selectivity such that light having a predetermined wavelength is resonantly reflected.

    Abstract: The present invention provides a small spectrocsope that has a short response time. A spectroscope according to an embodiment includes a beam deflector that includes an electro-optic crystal, having an electro-optic effect, and paired electrodes used to apply an electric field inside the electro-optic crystal; spectroscopic means for dispersing light output by the beam deflector; and wavelength selection means for selecting light having an arbitrary wavelength from the light dispersed and output by the spectroscopic means. At the least, either an input end or an output end of the beam deflector is wedge shaped, so that a thickness of the end is gradually reduced from the first face, where the first electrode of the paired electrodes is located, toward the second face, opposite the first face, where the second electrode of the paired electrodes is located.

    Abstract: The present invention provides an autofocus mechanism for a spectroscopic system (400) that is adapted to determine a property of a volume of interest. The volume of interest has an optical property that varies with time. The invention provides measurement means that are adapted to measure the fluctuations of the optical property of the volume of interest for determining the position (428) of the volume of interest. The spectroscopic system being further adapted to focus an excitation beam (418) into the determined volume of interest and for collecting return radiation (420) emanating from the volume of interest for spectroscopic analysis. Preferably, inelastically scattered radiation of an excitation beam (428) is separated from elastically scattered radiation for spectroscopic analysis. The elastically scattered radiation of the excitation beam is in turn exploited in order to measure the fluctuations of the optical property of the volume of interest. Making use of a control loop allows for maximization of the amplitude and/or intensity of the fluctuation inherently specifying the position of a volume of interest e.g. the center of a capillary vessel (450).
