## 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 there; ultrasonic sensors can't operate in vacuum at all.

## Detailed Answer

[Roll-2-Roll® Sensors](https://r2r.tech/products/sensors) are **vacuum compatible** and can detect clear films in vacuum environments. This addresses limitations other sensing technologies have in vacuum:

- 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 fiber-optic technology solves both problems, making it a strong fit for applications like:

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