Problems solved by technology
However, the uniformity data for each product is a value under different measurement conditions, not when incorporated and used in a measurement device such as a flow cytometer, and not within the wavelength range that each channel is responsible for , so an error occurs, and it is not feasible to reuse a reference spectrum just by performing this correction

Abstract
Provided is technology that enables quantitative data to be handled, without a degradation in SNR, in a spectrum-type microparticle measurement device. The present technology provides a microparticlemeasurement spectrometer that is provided with: a spectroscopic element for dispersing light emitted from microparticles flowing through a flow channel; and a photoelectric conversion array which hasa plurality of light-receiving elements of different detection wavelength regions and converts optical information, obtained from the light-receiving elements, into electrical information, wherein theoutput of all channels is uniform in the photoelectric conversion array when light having the same light quantity per unit wavelength is incident thereon.
Description
technical field [0001] This technology relates to particle measurement spectrometers. More specifically, the present technology relates to a particle measurement spectrometer for detecting optical information of particles flowing in a flow path, a particle measurement device using the particle measurement spectrometer, and a method for calibrating a particle measurement photoelectric conversion system. Background technique [0002] In recent years, with the development of analytical methods, a method has been developed in which fine particles such as biological fine particles (eg, cells and microorganisms, microbeads, etc.) The measured particles are analyzed and classified. [0003] As a typical example of such a method for analyzing or classifying microparticles, technological improvement of an analysis method called flow cytometry has been rapidly developing. Flow cytometry is an analysis method in which microparticles to be analyzed are poured into a fluid in an aligne...
