WebThe CIE has recommended in CIE 127 that LEDs be measured using 2° and 6.5° geometry, and that these two readings are averaged to yield "Averaged LED Intensity." A typical LED receptor is a tube in which one end is attached to the light measuring device and the other end receives the LED. WebAn ODMR member is arranged in a measurement target AC magnetic field. A coil applies a magnetic field of a microwave to the ODMR member. A high frequency power supply causes the coil to conduct a current of the microwave. An irradiating device irradiates the ODMR member with light. A light receiving device detects light that the ODMR member emits.
