Infrared (IR) radiation is electromagnetic radiation which has a longer wavelength than visible light but is shorter than terahertz radiation and microwaves. The name means "below red" (from the Latin language) and red is the color of visible light with the longest wavelength. Infrared radiation has a wavelength between about 750 nm and 1 mm, spanning three orders of magnitude.
Infrared imaging is widely used for military and civilian purposes. Military applications include target acquisition, surveillance, and night vision, homing and tracking. Non-military uses include thermal efficiency analysis, remote temperature sensing, short-range wireless communications, spectroscopy and weather forecasting. At the atomic level, infrared energy causes modes of vibration in molecules through changes in dipole moment, making it a useful frequency range for studying these states. Infrared spectroscopy examines the absorption and transmission of photons in the infrared energy range based on their frequency and intensity.

Be aware of IR light hazard
Infrared rays may damage the eyes. The eye does not react to infrared light generated by the infrared LED; the pupil does not respond to protect the retina. Then the retina can easily be over-exposed to the infrared light produced by the LED.
The bright, natural light, which contains infrared light, blinks the eye, the iris contracts, and the viewer looks away. These normal defense mechanisms do not happen, and when the visible part has been removed, it is exactly where infrared illumination takes place. Your eyes are more sensitive than your skin, and excessive contact may cause retinal damage and cataracts.
So how do you protect yourself? The rule of thumb is not to look into infrared light sources for long periods of time and to work within the minimum safe working distance, which is typically at least half the effective distance of the luminaire. For example, if you are using a luminaire that is 12 feet (365cm) apart, you want to be at least 6 feet (182cm) away and you should not look into it for an extended period of time.
Dinam offer IR at 850nmwavelength, and variables consists of 12V or 24V, 5050 or 3528, and density on pcb.
