The structure of high-speed optocoupler is different from ordinary optocoupler. The structure of high-speed optocoupler is photodiode + amplifying drive circuit, and the structure of ordinary optocoupler is phototransistor (+amplifying drive circuit). The response speed (rise and fall time) of the photodiode is in the       order of nanoseconds, and the response speed (...

     Many outdoor products also use infrared transmitter tubes and infrared receivers as the first choice for remote control or data transmission solutions. However, because the outdoor light is relatively sufficient, especially when the sun is clear, the infrared receiver often fails. After discussing with some customers, the basic solution is as followsFirst understand the reasons...

Reflective photoelectric switch is also an infrared invisible light product. It is a small photoelectric component that can detect the change of the light intensity it receives. In the early stage, it is used to detect whether the object is sensed. It is composed of an infrared emitting tube and an infrared receiving tube. Its emission wavelength is 780nm-1mm. The transmitter has a calibration len...

      About the introduction of LED applications in different bands, UV LED, visible light LED, infrared light LED, some commonly used LED light sources, what are the special use channels?       1.UVLED (ultraviolet LED):　　(1) Low UV: 250nm-265nm-285nm-365nm, now it can achieve 250nm-410nm. These are all INGaN/GaN material carbides. These ultraviolet rays can k...
