Camera CMOS is extremely fragile and the potential for damage to camera CMOS, either directly or indirectly ( laser beam reflected from a reflectingobject is high in outdoor or indoor environments when laser display devicesare present. There have been countless cases of camera sensor damage due tolaser exposure, such as in parks, weddings, bars, concerts and other scenarios.

Generally common laser pointer power in 1 milliwatt to 5 milliwatt, while thestage laser light power may reach more than 10 watts , buildings, landmarksused by the laser modeling lights and even up to 40 watts.

When the scattered laser at a certain moment directly or reflected directly intothe camera and the camera does not filter light measures , ray photons in theobject through the process will produce induction current in the object , the in -duction current will produce an electric field , so that the object particles osciltion, and into the thermal effect. And the camera module will use organic com -pounds for vapor deposition during the manufacturing process, when subjected to high temperature, the structure of the coating layer is changed, then thecamera will be damaged.

Depending on the degree of damage, the phenomenon is also different. In light cases, red / purple / blue spots will appear on the screen , and in heavycases, vertical / horizontal streaks will appear on the screen , or the screen will be faded.

So how do we avoid laser damage to the camera ?
We have a laser source in the vicinity of the shooting, try to avoid the direct angle of the laser . When shooting to close the aperture, the aperture blade willcover the light path, reducing the area exposed to the photographic chip , whichin turn reduces the probability of injuryBut this can not all avoid laser damage, there will still be a probability ofdamage to CMOS , after all , the diffuse laser can not be controlled.

So how do we play in such scenes the advantages of our camera and protectthe camera from damage?
