  • PDA-Photo diode

Ultraviolet (UV) :

  • Electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.

Refractive index :

  • The refractive index, also known as the index of refraction, is defined as the ratio of the velocity of light in vacuum (or air) to its velocity in a transparent medium.
 Refractive Index(RI)

Refractive Index(RI)

PDA - Photo Diode :

  • A photodiode is a semiconductor device that converts light into an electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas.
