What three sections makeup the Electro-Optics (EO) portion of the Electromagnetic (EM) spectrum?

The Electro-Optics (EO) portion of the Electromagnetic (EM) spectrum is primarily characterized by three distinct sections: Ultraviolet, Visible, and Infrared.

Ultraviolet light is shorter in wavelength than visible light and is not visible to the human eye. It can have applications in various fields, such as spectroscopy and fluorescence.

The Visible spectrum encompasses the range of light that is perceptible to the human eye, typically ranging from about 400 nm (violet) to 700 nm (red). This section is crucial because it encompasses the light that we actively see and interact with on a daily basis.

Infrared light has longer wavelengths than visible light, ranging from about 700 nm to 1 mm. Infrared technology is commonly used in applications such as thermal imaging, which detects heat signatures, and various types of remote sensing.

Each of these three sections plays a significant role in different applications, particularly in military and surveillance contexts, where EO systems rely on detecting and analyzing these portions of the spectrum for various operational needs.
