Optical power meter คือ
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters (can be … See more The major semiconductor sensor types are Silicon (Si), Germanium (Ge) and Indium Gallium Arsenide (InGaAs). Additionally, these may be used with attenuating elements for high optical power testing, or wavelength … See more A class of laboratory power meters has an extended sensitivity, of the order of -110 dBm. This is achieved by using a very small detector and lens combination, and also a mechanical … See more Optical power meters usually display time-averaged power. So for pulse measurements, the signal duty cycle must be known to calculate the peak power value. However, the instantaneous peak power must be less than the maximum meter reading, or the … See more A typical OPM is linear from about 0 dBm (1 milli Watt) to about -50 dBm (10 nano Watt), although the display range may be larger. Above 0 dBm is considered "high power", and … See more Optical Power Meter calibration and accuracy is a contentious issue. The accuracy of most primary reference standards (e.g. Weight, Time, Length, Volt, etc.) is known to a high accuracy, typically of the order of 1 part in a billion. However the optical power … See more • Measuring the absolute power in a fiber optic signal. For this application, the power meter needs to be properly calibrated at the wavelength … See more Typical test automation features usually apply to loss testing applications, and include: • The ability to set the unit to read 0 dB at a reference power … See more http://www.scmashopping.com/category/70/environmental-test-measurement-wind-speed-light-sound-ph-gas-meters/3-8-conductivity-meters-%E0%B9%80%E0%B8%84%E0%B8%A3%E0%B8%B7%E0%B9%88%E0%B8%AD%E0%B8%87%E0%B8%A7%E0%B8%B1%E0%B8%94%E0%B8%84%E0%B9%88%E0%B8%B2%E0%B8%84%E0%B8%A7%E0%B8%B2%E0%B8%A1%E0%B8%99%E0%B8%B3%E0%B9%84%E0%B8%9F%E0%B8%9F%E0%B9%89%E0%B8%B2%E0%B8%82%E0%B8%AD%E0%B8%87%E0%B8%82%E0%B8%AD%E0%B8%87%E0%B9%80%E0%B8%AB%E0%B8%A5%E0%B8%A7
