Embodiment Construction

[0057] In the particle analysis device of the present invention, conventional complicated components for an optical system are not used on the light source side, but a light beam is formed through a small light-transmitting hole formed in an opaque film, and the light beam reaches an illumination point. With such a configuration on the light source side, many parts in the optical system are omitted to enable miniaturization of the entire device, and also reduce the cost of the parts.

[0058] In addition, since the optical path of the light beam is determined by the position of the light-transmitting hole formed in the opaque film, it is possible to align the position irradiated by the light beam in the flow channel with high precision. Therefore, steps of alignment and focusing of irradiation light by many optical system components can be omitted, and assembly costs can also be reduced.

[0059] Regarding the photodetector side, in the embodiment in which the flow channel is ...

Abstract

An apparatus including a flow cell part 1 having a flow channel 11 where the sample solution containing the particles to be analyzed flows; a light irradiation device 2 for irradiating an irradiation light L1 as a beam light L2 to a light irradiation point in the flow channel; and a light receiving device for detecting the light L3 resulting from the irradiation of the beam light L1 to the light irradiation point. The light irradiation device 2 has a light source device Ls and a beam-light-forming-film 21 composed of an opaque film 22 and a light transmitting hole 23 formed in the film 22. Using the light transmitting hole 23, the cross sectional shape of the irradiation light L1 is changed to that of the beam light L2, whereby optical apparatuses such as lens and the like on the irradiation side are omitted.

Description

technical field [0001] The present invention relates to a particle analysis device for analyzing particles such as blood cells in a liquid at least according to flow cytometry and a method of manufacturing the particle analysis device. Background technique [0002] As a method for optically analyzing and counting blood cells such as red blood cells, white blood cells, and platelets in blood, flow cytometry is known. Flow cytometry is a technique including the steps of irradiating predetermined irradiation light as a light beam focused on blood cells in a sample solution (sample liquid) advancing through a flow channel, and based on obtained optical characteristics such as light scattering and light absorption, to distinguish blood cells (for example, Patent Document JP-A-H8(1996)-327529). [0003] Figure 9 is a cross-sectional view of a configuration example of a device used for flow cytometry. The device shown in this figure is also known as a flow cytometer. [0004] A...
