## Question

Can Roll-2-Roll sensors work in vacuum environments?

## Short Answer

Yes. Roll-2-Roll sensors work in vacuum environments and can detect clear films under vacuum—a capability no ultrasonic sensor can match.

## Detailed Answer

[Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) are **vacuum compatible** and can detect clear films in vacuum environments. This is a unique capability that no other edge detection technology can match:

- Ultrasonic sensors cannot function in vacuum—no air means no sound waves for detection
- Many optical sensors struggle with clear films even in normal atmosphere

[Roll-2-Roll Technologies](https://r2r.tech) fiber-optic technology solves both problems, making it the only solution for applications like:

- Glass manufacturing processes
- Vacuum coating operations
- Semiconductor manufacturing
- Specialty film production
