LED Emitters are semiconductor devices that emit light when current flows through it. This category includes Infrared (IR), Ultraviolet (UV), and Visible. Infrared (electromagnetic radiation) is invisible to the human eye with wavelengths from around 700-800 nanometers (nm) to 1 millimeter (mm). IR is commonly used in heat sensors, thermal imaging, and more. Ultraviolet rays are invisible to the human eye, ranging from around 200 nm to 400 nm. UV is commonly used for curing resin, killing bacteria, and more. Visible emitters exist in the wavelength range from around 400 nm to 700-800 nm. This category can be sorted by type, forward current, wavelength, viewing angle, forward voltage, operating temperature, and more.

Understand how a comparator switches at a voltage threshold, why hysteresis prevents chatter, and which output and input specs matter.
