Infrared infrared laser belongs to

CodePudding user response:

They are the same

CodePudding user response:

Short wave infrared, should be the same

CodePudding user response:

Each sensor (including emission with leds, laser head; Receive with photosensitive diode) has a frequency response curve
From the strict sense, the infrared refers to the electromagnetic wave frequency is below a certain boundary
We use the infrared receiving photodiode, also will be affected by the visible light!!!!! Just watch it frequency response curve will be found, it mainly in the infrared region of high sensitivity,
We often use the infrared laser, specific see the device, even though the frequency of the laser are very single, but still there will be a small amount of other frequency component, which our eyes can see a lot of red visible light component,
Do you belong to the infrared light asked infrared laser?
First, are you sure good infrared light and infrared light line
Second, you have to watch what you say infrared laser specific parameters
