OP916

Optical sensors are composed of two parts: the detector and the receiver. Photodiodes are the primary choice of detector for modern optical sensor systems. An OP916 is an example of a photodiode-based optical sensor designed for mid-wave infrared (MWIR) applications. By analyzing its working principle and understanding its application field, one can better understand the use of this specific type of optical sensor in many applications.

The OP916 is a MWIR optical detector with a GaAs/Bi/Sb-barrier type structure. It is made of a p-type area with an n-type-barrier region. This barrier region is where the MWIR radiation is absorbed. When MWIR radiation is absorbed by the barrier layer, the electrons are excited from the valence band of the barrier structure into the conduction band. This results in the flow of electrons across the barrier and the generation of an electric current. This current is then amplified and measured by a receiver, thereby capturing a quantum measurement of the radiation.

The OP916 has a number of unique features that make it ideal for certain applications. Firstly, it has a spectral response range between 3 and 11 µm which enables it to measure small changes in the MWIR radiation. Its excellent responsivity and high sensitivity make it ideal for applications such as flame detection, combustion analysis, solar energy measurement, and thermography. In addition, the OP916 is able to provide extremely accurate temperature measurements over a wide range since it has an operating temperature range of -40°C to +105°C.

The most impressive feature of the OP916 though is its ability to deliver high-resolution data. This is achieved through a number of sophisticated technologies such as micro-integrated thermal protection which enabled multi-pixel measurement and avoids any data loss due to the high thermal levels. Additionally, the OP916 was designed with an on-board signal-processing circuit which is able to offer a fast response to magnitude and varying temperatures while suppressing background noise. The result is a highly accurate device well suited for precise data gathering and analysis.

Overall, the OP916 is a state-of-the-art MWIR photodiode designed for many different applications. It features an excellent spectral response range, high sensitivity, wide temperature range, and multiple integrated technologies that enable accurate and reliable measurement. From flame detection to solar energy measurement, the OP916 is ideal for a variety of different applications that require MWIR detection and accurate data gathering and analysis.
