Understanding Infrared
Infrared Spectrum
Infrared (IR) radiation is a type of electromagnetic radiation that has longer wavelengths than visible light. The IR spectrum ranges from about 700 nanometers to 1 millimeter in wavelength. The human eye cannot detect IR radiation, but it can be detected as heat. IR radiation is emitted by all objects with a temperature above absolute zero.
Visible Spectrum
The visible spectrum is the range of electromagnetic radiation that can be seen by the human eye. It ranges from about 400 to 700 nanometers in wavelength. The colors of the visible spectrum are red, orange, yellow, green, blue, indigo, and violet.
Radiation
Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. IR radiation is a type of non-ionizing radiation, which means it does not have enough energy to remove electrons from atoms or molecules, but it can still cause heating effects.
Infrared flashlights are designed to emit IR radiation, which is invisible to the human eye. They are often used in conjunction with night vision equipment to illuminate an area without being detected by the naked eye. IR flashlights work by using LEDs that emit light in the IR spectrum. The light emitted by the LEDs is then reflected off of objects and detected by the night vision equipment.
Overall, understanding the IR spectrum, visible spectrum, and radiation is essential to understanding how IR flashlights work and their applications.
