Abstract:
A measuring device (100) comprising a cofocal-point optical microscope (110), an excitation light source unit (130) that emits an excitation light for generating fluorescence from a fluorescent material, and a light receiving unit (140). The cofocal-point optical microscope (110) has an excitation light input port (112) for capturing an excitation light from the excitation light source unit (130), and an output port (113) for outputting fluorescence generated by an excitation light. The light receiving unit (140) has an input unit (141) for capturing a signal light including fluoresence from the microscope (110). The input unit (141) of the light receiving unit (140) is optically connected to the output port (113) of the microscope (110) via an optical fiber (153).
Abstract:
A retention mechanism for an immersion medium (31) for use in a device which observes/measures a sample by use of an objective lens (10), wherein a member for retaining the immersion medium near a tip portion of the objective lens is constituted by a first material (± portion) having a low affinity with the immersion medium, and a second material (² portion) which has a high affinity with the immersion medium, the retention mechanism being provided with a supply unit (34) and a drip draining unit (35) for supplying respectively draining the immersion medium.
Abstract:
Onto a surface of an Al x Ga y In 1-x-y As z P 1-z (0¤x, y, z¤1) layer including GaAs alone or an InP substrate, an electron beam controlled to an arbitrary electron beam diameter and current density is irradiated so as to selectively substitute or generate Ga 2 O 3 for a natural oxide layer formed on the Al x Ga y In 1-x-y As z P 1-z layer surface, then the Al x Ga y In 1-x-y As z P 1-z layer surface is dry-etched by a bromide in single atomic layer units, whereby the natural oxide layer other than the part substituted by the Ga 2 O 3 and Al x Ga y In 1-x-y As z P 1-z substrate are removed.
Abstract:
The present invention aims to provide an analyzing method of a feeble light image for quickly and correctly analyzing an image of a biological specimen that emits a feeble light. In the present invention, when analyzing an image of a biological specimen that emits a feeble light, at least one reference position relating to a target region to be analyzed of the biological specimen is determined by using electromagnetic energy that is different from the feeble light to the target region, a focal position for the feeble light corresponding to the target region with respect to the reference position is determined, an image according to the feeble light is formed by performing a focusing onto the determined focal position, numerical values of necessary measurement parameter are extracted from the feeble light image, and the evaluation of the target region is carried out based on the extracted numerical values of the parameter.
Abstract:
The present invention aims to provide a focal position determining method, a focal position determining apparatus, and the like that can determine the focal position of the objective lens focused on an observed target region at the time of setting a specimen, when a specific region in a specimen is defined as the observed target region, and the luminescence of the observed target region is observed. In the present invention, light is irradiated to the specimen, the focal position of the objective lens is changed, the changed focal position is measured, the specimen to which the light is irradiated is imaged at the changed focal position, feature data is calculated based on the imaged image, the process of changing the focal position, the process of measuring the focal position, the process of imaging the specimen, and the process of calculating the feature data are repeatedly executed, at least one focal position is selected from the accumulated plural focal positions by the execution based on the plural feature data accumulated by the execution, and the focal position of the objective lens focused on the observed target region in the specimen is determined based on the selected focal position. The focal position of the objective lens is determined, and then, a digital zooming and optical zooming are performed to magnify the imaged image with a desired magnification for display.
