Optical sensor detects mirrored and transparent surfaces reliably

01 June 2016

A high performance optical sensor that can reliably identify mirrored, transparent, diffuse and other hard to detect surfaces has been launched by Omron.

The new Omron B5W Light Convergent Reflective Sensor detects target objects much more reliably than general reflection photo sensors, even those that are often a challenge such as reflective, transparent, diffuse or black surfaces. The sensor’s convergent light beam can be accurately set to trigger on the presence of an object within a tightly specified target area, and ignore any objects in the background or foreground. The B5W features a combination of a cylindrical and a non-spherical lens. 

A typical application is a step detection function in a robot device. The B5W can reliably distinguish wood, glass, carpet and other floor surfaces from a downward step, to avoid risk of the robot falling. 

The B5W can detect objects over a maximum distance of 70mm and provides an analogue output signal.
