infrared - Dangers of IR LED - Electrical Engineering ...

· Since I want to focus the light (maybe one or two degrees divergence after the lens) , I started thinking about potential dangers to the eye. Reading up on the topic reveals that IR light can be very problematic. The eye doesn't see the IR wavelengths and can't react to overexposure. Therefore it is crucial to be well within the limits of safety standards.

Infrared Thermometers, are they Safe?

It is necessary to keep the sensor of the Infrared Thermometer clean and dry Remember, measurements are not a substitute for a doctor's diagnosis. As long as the Non-Contact Infrared Thermometers are used properly, they do not represent a risk of possible eye damage, as these Thermometers do not use lasers to measure body heat, the authorized thermometers measure infrared light; therefore they are not …

Infrared Light - an overview | ScienceDirect Topics

Infrared light is used because the native sensitivity of the Silicon (CCD and CMOS sensors) has very good sensitivity in and near the infrared region. These are the wavelengths longer than 700 nm. As mentioned at the beginning of this book, the human eye can see up to 780 nm, with the sensitivity above 700 nm being very weak, so in general we say that the human eye only sees up to 700 nm.

What are the Dangers of Infrared? | Healthfully

· Safety Hazards of Infrared. Since IR radiation only works to get molecules moving, any moderate dose of IR radiation will simply heat up any living tissue it touches upon. The only hazard in most cases is that prolonged exposure to a very high level of IR could result in a burn, just as could exposure to a hot stove or any other heat source. The one exception is that workers who are exposed …

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.
