Introduction

PDB-V613-2 is a type of photodiode, which is a kind of optical sensor which has wide application. It is widely used in many kinds of applications, such as surveying, astronomy, laser scanners etc. The working mechanism of PDB-V613-2 is relatively simple. It uses a few components to detect light and convert it into electrical signals.

Application

PDB-V613-2 is an attractive photodiode because of its relative simplicity and low cost. It can be used in applications which require detection of relatively weak signals and current which can be in the range of femto amps to pico amps.Surveying instruments for example may require the detection of light sources like stars, which can be implemented with PDB-V613-2. Astronomers may also find it helpful in detecting faint source objects. Laser scanners used in various industries such as 3D printing or medicine may also use PDB-V613-2 to detect faint laser points.

Working principle

PDB-V613-2 consists of an input, an active area, and an output. The input is the place where light is detected and is usually formed by an optical filter. The active area is usually a PIN photodiode or an avalanche Photodiode (APD). The output is the place where the signal is detected. The PIN photodiode works on a very basic principle that is the electron-hole recombination which occurs under the influence of light. The photons of light in this case, are absorbed in the active area of the photodiode and creates electron-hole pairs. This creates an electric current and voltage in the output of the device. The avalanche photodiode on the other hand, works on the principle of avalanche breakdown which is caused by the electric field created due to the accumulation of electrons and holes on its active region when exposed to light. This avalanche breakdown generates current in the output of the device.

Conclusion

PDB-V613-2 is a widely used optical sensor whose working principle is based on PIN photodiode or avalanche photodiode. It is widely used in applications which require the detection of faint signals like in surveying, astronomy, and laser scanning. Because of its relative simplicity and low cost, it is an attractive option in many different industries.
