  • Patent number: 10302612
    Abstract: Provided is a hydrogen concentration measuring device capable of measuring with high accuracy a hydrogen concentration over an extensive range by a simple configuration. The device includes: a sensor chip which detects the electric resistance of a sensing film; an optical measurement unit which detects the transmitted light intensity of the film; and a controller. The controller performs measurement processing such that a hydrogen concentration in the gas atmosphere is measured based on the detected electric resistance in a first measurement range and based on the detected transmitted light intensity in a second measurement range and is determined so as to reduce a difference between the hydrogen concentration based on the detected electric resistance and the hydrogen concentration based on the detected transmitted light intensity in the overlap of the first measurement range and the second measurement range.

  • Publication number: 20180045508
    Abstract: An interference fringe generating optical system generates an interference fringe, and a magnifying optical system magnifies the interference fringe and projects the interference fringe on an object surface. The magnifying optical system includes an incident-side lens group on the side where a light beam forming the interference fringe is incident and an exit-side lens group on the side where the light beam is emitted and the interference fringe is projected towards the object surface. The expression f1/f2>3 holds, where f1 is the focal length of the incident-side lens group, and f2 is the focal length of the exit-side lens group. The incident-side and exit-side lens groups each have a positive refractive power. The expression xd/(f1+f2)<2 is satisfied, where xd is the distance from the exit-side principal point of the incident-side lens group to the incident-side principal point of the exit-side lens group.
