Embodiment Construction

[0040] Hereinafter, an evaluation method of an optical analysis device and a phantom sample 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0041] The phantom sample 1 involved in this embodiment is as figure 1 As shown, a plurality of two types of solid members 2 and 3 having different fluorescent substance concentrations are alternately adjacently arranged to form a flat plate shape.

[0042]One solid member 2 contains a fluorescent substance having a predetermined fluorescent concentration. The other solid member 3 does not contain a fluorescent substance (contains a fluorescent substance whose fluorescence concentration is zero.). These solid members 2 and 3 are formed extremely thin, and their width dimensions are set to the same width dimension with high precision.

[0043] Hereinafter, an evaluation method of an optical analysis device using the phantom sample 1 according to the present embodiment configured i...

Abstract

The purpose of the present invention is to easily and accurately evaluate an optical system of a light analyzing device. Provided is an evaluation method for a light analyzing device, comprising an optical system (A) capable of forming a confocal volume (C) at a focal point by concentrating excitation light (B), that includes: a step of disposing a phantom sample (1) that is made by arranging a plurality of solid members (2, 3), which are of two or more types having different concentrations of a fluorescent material, to be adjacent in the focal point of the optical system (A); a step of moving the confocal volume (C) formed by the optical system (A) relative to the phantom sample (1) in the direction that the solid members (2, 3) are arranged and emitting the excitation light onto the phantom sample (1) via the optical system (A); a step of detecting fluorescent light generated by the solid members (2, 3) disposed in the confocal volume (C); and a step of evaluating the optical system (A) on the basis of the detected fluorescent light.

Description

technical field [0001] The invention relates to an evaluation method of an optical analysis device and a phantom sample. Background technique [0002] Conventionally, an optical analysis device is known (for example, refer to Patent Document 1.) that can quantitatively observe phases that can be processed by optical analysis techniques including statistical processing such as fluorescence correlation spectroscopy (Fluorescence Correlation Spectroscopy: FCS). The state and characteristics of luminescent particles in an aqueous solution with a lower concentration. [0003] This optical analysis device uses an optical system capable of detecting light from a confocal region (confocal region) in an aqueous solution, such as a confocal microscope or a multiphoton excitation microscope. Then, when the position of the confocal region is moved in the aqueous solution, that is, while scanning the aqueous solution through the confocal region, it is detected that light-emitting partic...
