Photodiodes are a type of optical sensors used to measure optical properties, such as light intensity, light power, spectral group, and spectral characteristic. The VEMD2000X01 is a photodiode designed for use in a variety of applications. To understand how the VEMD2000X01 works, it is important to understand the basics of photodiode operation.

The Basics of Photodiode Operation

A photodiode is an electronic device that emits and detects light. When a photon of light strikes the photosensitive region of a photodiode, it generates an electric current. The current produced is proportional to the photon’s energy, and the strength of the current is known as the photoelectrical effect. By measuring the current produced when light is detected, the photodiode can be used to measure the intensity of a light source.

The photodiode is a current-mode device. It has two terminals, a cathode and an anode, and a photosensitive region. When a photon strikes the photosensitive region, it generates an electric potential, which causes current to begin flowing through the device. The current is proportional to the number of photons incident on the photosensitive region. By measuring the current produced, the intensity of light can be detected.
