Optical Sensors - Photodiodes

Photodiodes (PDs) are a type of optical sensor that can detect visible and near infrared radiations from its surroundings. They are often used in industrial applications, such as optical detectors for medical imaging, light sensors, and photovoltaics. The most commonly used type of PDs is the PIN diode, which is the most widely used type of photodiode.

PDB-C119 is a type of PIN (PN) photodiode designed to detect optical radiation from visible and near infrared ranges. It is available with active area 3x3 mm2, and peak wavelength sensitivity at 1.117 μm (Infra-Red with peak at 880 nm). One of the key features of this PD is its high power handling capability of up to 20W/Sr. Its Pd peak sensitivity wavelength is 880nm and the spectral range is from 450-1050nm. This makes it well suited for applications like infrared (IR) LED detection.

The working principle of a PDB-C119 photodiode is quite simple. When exposed to light, the PD absorbs photons, and the photons give the electrons kinetic energy, which raises the electron\'s energy level. At this point, the electrons are in the so-called conduction band, which means they can pass through the external circuit. This is the photocurrent. With the external circuit, the electrons can be manipulated, collected, and measured, allowing the image on the screen to be converted into a digital signal, thus enabling the user to see the image or monitor the changes in the vicinity.

PDB-C119 photodiodes have a wide range of applications, such as in infrared imaging systems, fiber optical communication systems, astrophysics, optoelectronic device testing for medical imaging systems, and optical sensor monitoring. For example, in medical imaging systems, the photodiode is used to detect signals from the radiation emitted by a patient’s body, while in optical sensor monitoring, it is used to detect changes in the outside environment. Furthermore, due to its high power handling capability, it can be used in high intensity lighting applications such as fiber optics. Finally, due to its high sensitivity, it is also suitable for weak optical signals detection.

In conclusion, PDB-C119 photodiodes are a very versatile type of optical sensors and can be used in a variety of applications. The design of the PD has many advantages, such as high power handling capability, spectral range from 450-1050nm, and high sensitivity. All these attributes make the PDB-C119 photodiode a reliable, efficient, and cost effective optical sensor choice for various applications.
