Composition of infrared night vision lens

What are the components of an infrared night vision lens 1. Infrared light board (Infrared night vision lens) After power on, the current is transmitted to the infrared wick which can convert electrical energy into light energy and heat energy through the PCB circuit board, and the infrared light is emitted from the infrared light and projected onto the object. 2. Lens (infrared night vision lens) Collect the infrared light reflected by the infrared lamp projected on the object, and send it to the camera board after focusing processing and imaging. Optical components (CCD/CMOS). 3. Camera motherboard Photosensitive components (CCD/CMOS) convert the received infrared light imaging from light into current signals, which are transmitted to various working IC electronic components for processing via the PCB circuit board, and finally converted into video signal output by the micro-processing chip (DSP) . 4. Camera shell Fix the combination of the above components to protect the above components to achieve the effects of waterproof, dustproof, and an
