Optical sensors are electronic devices used to detect and measure light. They can detect a wide range of visible and near infraredlight frequencies, making them invaluable and versatile products in a wide range of industries. As such, they are becoming increasingly important components in industrial production, manufacturing, defense, medical, and other settings. The 70156-4606 is an optical sensor that is widely used in industrial applications. This article will discuss its application field and working principle.

70156-4606 Application Field

The 70156-4606 is a Silicon-on-Glass (SoG) photodetector. It is used in a variety of industrial applications and physical processes including:

• Optical sensors for monitoring, detection and measurement
• Driverless automotive
• Biomedical imaging
• LIDAR for autonomous vehicles
• Robotic vision
• Artificial intelligence
• Scientific research
• Security systems

The 70156-4606 is particularly useful in applications where very low noise performance and high sensitivity are desired. As such, the sensor is particularly useful in low light level applications.

70156-4606 Working Principle

The 70156-4606 is an active photodetector that utilizes a Photomultiplier Tube (PMT) to convert an optical signal into an electrical one. The PMT consists of a cathode, multipler electrodes and an anode. The cathode is a photocathode that is illuminated by a light source and converts the photons into electrons. The electrons are then accelerated by a potential difference between the cathode and the first dynode (the multiplier electrode). The electrons then hit the first dynode and cause it to emit additional electrons, which are then accelerated by the potential difference between the first and the second dynode. This process continues on through the remaining dynodes until finally, the electrons are collected by the anode at the end. The resulting current is then converted into a voltage signal that can be used by the sensor.

In addition, the 70156-4606 has a very low noise level and a very high signal output, even at low light levels. This is because the sensor has an integrated Schottky Barrier Detector (SBD), which is very sensitive to light in the near Infra-red (NIR) range and can produce a signal even at very low light intensities. The SBD is also able to produce a signal without the need for complicated amplification.

Conclusion

The 70156-4606 is an optical sensor that is widely used in industrial and scientific applications. It utilizes a Photomultiplier Tube to convert an optical signal into an electrical one and an integrated Schottky Barrier Detector to detect very low light intensities. As such, it is ideal for applications where very low noise performance and high sensitivity are desired.
