Optical Power Meter Small Module Can Be Used Independently With Built-In Chassis
The single channel optical power meter module converts the received optical signal into an electrical signal through the photoelectric effect, and then measures and displays the power of the optical signal. It is mainly used in optical fiber communication, optoelectronics, optical measurement and other fields to accurately measure and monitor the power of the light source.
Working principle
The working principle of single-channel optical power meter module is based on the detection and processing of photoelectric effect and electrical signal. Specifically, when light strikes a photosensitive element (such as a photodiode), the energy of the photon is converted into the kinetic energy of the electron, which creates a current or voltage in the photosensitive element. This weak electrical signal is then amplified, filtered, analog-to-digital conversion and other processing steps, and finally converted into a digital signal and displayed on the display screen of the instrument or presented to the user through the computer interface.
Main feature
High-precision measurement: Single-channel optical power meter modules usually have high-precision power measurement capabilities to ensure accurate measurement results even at low power conditions.
Wide wavelength range: In order to accommodate the operating wavelengths of different lasers, the single-channel optical power meter module needs to cover a wide wavelength range.
Fast response: Some applications need to measure rapidly changing optical power, so the single-channel optical power meter module needs to have fast response characteristics.
Environmental adaptability: Optical power meters are often used in various environments, such as laboratories, industrial production lines, etc., so single-channel optical power meter modules need to have good environmental adaptability.
