Color filters A color filter is any object that reflects or transmits light in a way that some color is observed. The color filters, as the name suggests, filters some parts of the electromagnetic spectrum of the sun (or Blackbody radiation spectrum). This wavelength spectrum is then sent to the

Absorbers An absorber is a device that partially or completely absorbs the incoming light or an EM wave for which it is designed. Absorption is one of the three phenomena that can happen to light as it hits the object. When light falls on an object, depending on the complex

Thin film interference Thin films (sometimes referred to as multilayer coatings) are layers of naturally occurring materials that are deposited in such a fashion that their thickness is small, in comparison to the wavelength of Electromagnetic (EM) waves they manipulate. Thin film interference can be used to calculate the behavior
