    Abstract: A low-cost laser power sensor having sufficient measurement accuracy with respect to received light intensity of the power sensor. The power sensor has a sensor substrate which receives monitor light, and a filter which attenuates the intensity of the laser beam before being received by the sensor substrate. The filter is constituted from a material having a laser transmissivity equal to zero, and has a plurality of openings within an irradiation range where the monitor light is irradiated. A summation of opening areas of the openings is equal to or more than 50% of the irradiation range. A part of the laser beam, which is irradiated to the filter and passes through the openings, is directly received by the sensor substrate.

    Abstract: A temperature compensation circuit for a light source (e.g., light emitting diode (LED)) whose radiant energy output decreases when ambient temperature increases includes a first circuit element for generating a first current that increases proportional to an increase in the ambient temperature, and a second circuit element for generating a second current that is first order independent of the ambient temperature. The circuit further includes a weighted current adder for generating a third current by combining the first and second currents with first and second weights applied to the first and second currents respectively. The circuit further includes a third circuit element responsive to the third current for supplying a fourth current to the light source to maintain a radiant energy output of the light source constant independent of the ambient temperature.

    Abstract: The present invention relates to a luminescence measuring device that includes a holder that holds a container for containing a sample, a plate member that holds the holder, a light detector that detects luminescence in the sample, and has a light receiving surface facing a bottom surface of the container, a first temperature control unit that performs control of a temperature of the light detector, and a ventilator that sends air to the light receiving surface of the light detector. The first temperature control unit may be provided on a side face of the light detector, and provided with a flow path therein. The air sending may be performed via the flow path in the first temperature control unit, so that the air having the same temperature as that of the light detector is sent to the light receiving surface.
