  • Detecting method, microarray analyzing method, and fluorescence reading device
    Patent number: 9823197
    Abstract: A detecting method includes irradiating a substrate having a concave and convex shape, with laser light collected by a lens; and detecting a height difference of the concave and convex shape by acquiring light intensity of reflected light and/or scattered light from the substrate as image data, and a light irradiation surface of the substrate is arranged at a position closer to the lens than a focal position of the lens is, reflected light and/or scattered light from the light irradiation surface is received as detected light, and a height difference of the substrate is detected based on a change in intensity of the received light.
