    Abstract: There are provided a cemented carbide high in thermal diffusivity and excellent in wear resistance, and a cutting tool including a base material formed of this cemented carbide. The cemented carbide is a WC based cemented carbide in which a hard phase mainly constituted of WC grains is bound by a binder phase mainly constituted of Co, and is used for a cutting tool. The binder phase is substantially constituted of Co, or Co and Ni. A total content of Co and Ni is not less than 4.5 mass % and not more than 15 mass %. In this cemented carbide, the WC grains have an average diameter of not less than 0.4 µm and not more than 4 µm. Assuming that the average diameter of the WC grain is represented by x (µm), the cemented carbide has a thermal diffusivity X (cm 2 /sec) satisfying X > 0.055x + 0.238. The cemented carbide can further contain one or more elements selected from Cr, Ta, Nb, Zr, and Ti at not less than 0.05 mass % and not more than 5 mass % in total.

    Abstract: A microscope that makes it possible to acquire a hyperspectral image with high data precision includes a light source, an illumination optical system, an image-forming optical system, an imaging unit, a spectroscope, a stage, a drive unit, and a control unit. The illumination optical system converges, at a converging angle ¸, illuminating light in a wavelength band included in the near-infrared region output from the light source, and emits the converged illuminating light onto the object being observed. The image-forming optical system forms an image based on transmitted and scattered light generated by the observed object by emission of the illuminating light onto the observed object. The sin ¸ is set to a value that does not exceed the numerical aperture of an objective lens that receives the transmitted and scattered light from the observed object.
