Two alternative reference light barriers for load-lock systems
The solution – variant 1
Our BOH optoelectronic sensors offer one variant for the implementation of a reference light barrier for wafer centering. They are available in a screw-in version made of rugged stainless steel housing with a sealing function and operate via micro-optics with a small light spot. You can comfortably make fine adjustments via an external amplifier.
The features
- Screw-in version
- Rugged stainless steel housing with sealing function
- Micro-optics with small light spot
- For vacuum applications down to 1x10-9 mbar
- Simple long-distance adjustment thanks to external amplifier
The solution – variant 2
Our BOH diffuse sensors or through-beam sensors with integrated micro-optics, which we would gladly tailor to your individual needs, are available to you as an alternative.
The features
- Integrated micro-optics for your individual frame
- For vacuum applications down to 1x10-9 mbar
