Iranian Scientists Produce Thermal Power Meter Sensor
“As one of the company’s knowledge-based products, this sensor has been able to meet the growing needs of various industries in the field of accurate optical power measurement,” said Amir Hossein Shahbazi, the managing director of the knowledge-based company.
Noting that the thermal power meter sensor is specially designed to measure the optical power of high-power laser sources, he said, “Using a special absorbent surface, this sensor absorbs a certain proportion of the radiation beam and converts it into heat. The high accuracy of this sensor is due to the basis of its operation, which is the measurement of heat flux.”
Shahbazi described the ability to measure the power of light sources in a wide range of wavelengths as another feature of the product, and said, “This allows users to use the thermal power sensor in various applications, including in the laser, medical, and research and development industries.”
Thermal Power Sensors are collectively able to detect power ranges from 10 µW to 200 W and wavelength ranges from 190 nm to 20 µm. These thermopile-based sensors are ideal choices for measuring broadband spectra from amplified spontaneous emission (ASE) sources, light emitting diodes (LEDs), filament lamps, swept-wavelength lasers, and other sources.
In addition, thermal power sensors do not saturate, which makes them well suited to measuring pulsed sources with high pulse peak powers or long-duration pulses.
These thermal power sensors also exhibit low dependency on the angle and position of the incident light beam. They are preferred for applications that cannot tolerate the strong wavelength dependencies and/or saturation thresholds of photodiode sensors. However, thermal power sensors generally have lower power resolutions and longer response times. We offer a wide range of thermal power sensors, with each including different design features.
