    Advantages of PID sensors
    The PID is a highly sensitive and versatile detector, and the PID can be viewed as a “low concentration LEL detector”. If you look at toxic gases and vapors as a big river, even if you swim into the river, the LEL detector may not respond, and the PID has already told you when you have just wet your feet.

    What are the uses and characteristics of fiber grating temperature measurement s...
    A fiber grating is a diffraction grating formed by axially modulating the refractive index of a fiber core by a certain method, and is a passive filter device. Because the grating fiber has the advantages of small size, small welding loss, full compatibility with fiber, and ability to embed smart materials, and its resonant wavelength is sensitive to changes in temperature, str...

  • The function of fiber collimator
    The function of fiber collimator
    The function of the fiber collimator is to convert the light output from the fiber into collimated light (parallel light), or to couple external parallel light (approximately parallel) into the fiber for transmission, so that the maximum efficiency of light can be coupled into the desired device.

  • The difference between FP laser and DFB laser
    The difference between FP laser and DFB laser
    The FP laser FP (Fabry-perot) laser is a semiconductor light-emitting device that emits multi-longitudinal mode coherent light with a FP cavity as a resonant cavity. FP lasers are mainly used for low-rate short-distance transmission. For example, the transmission distance is generally within 20 km, the speed is generally within 1.25 G, and the FP is divided into two wavelengths...

  • Fiber optic sensor principle
    Fiber optic sensor principle
    Fiber optic sensors are a new type of sensor that has evolved along with the development of fiber optic and fiber optic communication technologies. The fiber-optic sensor is corrosion-resistant, has little influence on the medium, and has strong anti-electromagnetic interference capability. Compared with the traditional sensors, the fiber-optic sensor uses light as a carrier fo...
