Detects Glass Substrates in Vacuum Chambers

Case Number 48

last update: November 4, 2009

This application uses a Photoelectric Sensor to detect transparent objects, including glass wafers.Through a view port, this Sensor can detect glass wafers that travel in a vacuum chamber. We used optical and circuit technology that detect minute signal differences of transparent glass.

Know-How

Conventional retroreflective photoelectric sensors could not provide stable detection of transparent glass with minute light attenuation.

Benefit / Efficiency

Our optimized optical and circuit technology provides stable detection of transparent glass.
