At present, the shortage of infrared cameras is easy to fog. In the face of such problems, our engineering companies will have headaches. We will receive calls from customers in three days and two. What kind of machine are you installing? It was not clear in a few days.
Some machines, even at room temperature, will fog up.
Infrared machines often fog, the solution is:
1, improve the motherboard current; 2, keep the machine dry
In fact, the fog is also related to the lens, and some manufacturers purchase some cheap raw materials in order to reduce costs. In terms of products currently on the market, it is conservatively estimated that there are 50% of unqualified products.
In fact, everyone talks about "fog," and most of them are not water vapor. Think about LED panels being so hot. Normally, the heater used to remove fog is not as hot as it is. Water vapor is evaporated. It looks like fogging. There are several reasons:
1. Lens shading light leakage and no close to the glass, infrared light refracted into the lens, especially 4mm most serious 2. The board itself parameters wrong, if just take the general board for a filter to use it, certainly a problem One day, but the day is still OK 3. The old problem: Overheating, CCD floats up on the white, it looks white
The water mist is mainly not waterproof enough, plus the humidity of the air, the heat generated by the infrared lamp and the CCD board will cause water mist.
Fogging should be caused by the camera's humidity rising rapidly at the camera's temperature, which is most serious when there is a wide gap with the outside temperature.
