Centricity Measurement in Substrate Production

LASER COMPONENTS invested further

Is the measurement of centricity in laser optics necessary or not? The more

optics that are used in a system, the more important the quality of each
individual lens becomes.

This is because optics which have a matching reference axis and optical axis
are a prerequisite for an optimal optical assembly - and only this makes it
possible to achieve lossless adjustment.

In a worst case scenario, deviations in the axes could lead to an undesired
heating up of the entire laser system. To ensure that the customers are on
the safe side with their laser optics, LASER COMPONENTS invested further and
provides the centricity measurement of individual lenses.

Centering errors can be measured in transmission and reflection. To
determine the centering accuracy, the tilting error of the top surface of
the sample is determined in relation to the edge and the bottom surface of
the lens.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
