    摘要： In an optical measuring device, the visual observation section includes: a white light source which emits white light; a first objective lens arranged between the white light source and measurement object, through which the white light emitted from the white light source and return light from the measurement object transmit; a plurality of tube lenses which change a magnification of the return light passing through the first objective lens to a predetermined magnification; and a lens switching mechanism which can selectively switch the tube lenses so as to select one of the tube lenses to be arranged on the return light, and the special observation section includes: a special light source which emits special light; and a second objective lens arranged between the special light source and measurement object, through which the special light emitted from the special light source and return light from the measurement object transmit.

    摘要： An illuminator includes: a light emitter including a light-emitting diode; a temperature sensor configured to detect a current temperature of the light emitter; and an illumination controller configured to adjust a drive voltage being supplied to the light emitter in accordance with the current temperature. The illumination controller includes a reference temperature storage in which a reference temperature is stored in advance and is configured to adjust the drive voltage by detecting the current temperature from the temperature sensor on a constant time cycle and comparing the current temperature with the reference temperature.
