Infrared light is electromagnetic radiation and is invisible to us. Other types of invisible light are microwaves, radio, gamma rays, x-rays, and ultraviolet light.
the temperature of a IR light is 6500 degrees fahrenheit
UV light has shorter wavelengths and higher energy than IR light. UV light is typically used for sterilization and disinfection, while IR light is used for communication, remote controls, and heating applications. UV light is also more harmful to living organisms, including humans, compared to IR light.
To increase the range of an IR sensor, you can use a more powerful IR LED as the light source, implement a lens to focus the emitted IR light, or amplify the sensor's output signal. Additionally, reducing interference from ambient light sources and optimizing the sensor's placement can also help extend its range.
Infrared (IR) radiation is distinct from ultraviolet (UV) radiation as they are found at opposite ends of the electromagnetic spectrum. IR radiation has longer wavelengths than visible light, while UV radiation has shorter wavelengths than visible light.
Blocking infrared (IR) light can significantly impact the performance of infrared sensors by reducing their ability to detect and measure infrared radiation. IR light is essential for these sensors to function properly, as it is the signal they use to detect and analyze heat signatures. Blocking IR light can result in decreased sensitivity and accuracy of the sensor, leading to potential errors or limitations in its performance.
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
An IR filter or IR cut filter is a color filter blocking infrared light. In order to avoid unwanted side-effects caused by infrared light during image recording in daylight mode. The filter is meant to prevent the incidence of light onto the image sensor.

Silicon is opaque to all light (IR through UV).The bandgap of silicon is not high enough to produce visible photons, only IR photons.
Ultraviolet (UV) light and infrared (IR) light are two types of invisible light. UV light has shorter wavelengths than visible light and can cause skin damage, while IR light has longer wavelengths and is commonly used in night vision technology.
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
