Introduction to Infrared Emitters

What are Infrared Emitters?

Infrared emitters are devices that produce infrared radiation, which is a form of electromagnetic radiation with longer wavelengths than visible light. These devices are widely used in various applications, ranging from consumer electronics to industrial processes. The primary function of an infrared emitter is to generate infrared light, which can be utilized for a multitude of purposes, such as communication, heating, and sensing. Infrared emitters come in various types, including LED (Light Emitting Diode) emitters, IR diodes, and IR lamps. Each type has its unique characteristics and applications. The choice of emitter depends on the specific requirements of the application, such as the desired wavelength, intensity, and power consumption.
