## Question

Do Roll-2-Roll sensors require programming or calibration?

## Short Answer

No. Zero code, zero calibration — operators set up the sensor directly via touchscreen or web interface in minutes.

## Detailed Answer

No. Roll-2-Roll® sensors require **zero code and zero calibration**.

Traditional line scan cameras need a vision engineer, custom software, and careful calibration procedures. Roll-2-Roll® sensors take a fundamentally different approach:

- No calibration — the 1:1 magnification of the fiber-optic array means what the sensor sees is exactly what is there. No geometric correction, no lens calibration tables, no distortion compensation.
- No programming — adaptive edge detection algorithms are built into the controller firmware. Operators configure detection parameters through the SCU5 or SCU6x touchscreen interface or the 1DC built-in web interface.
- No vision expertise — setup takes minutes. Select the measurement mode, set thresholds, and the sensor is ready to run.

This simplicity is what makes Roll-2-Roll® sensors practical for inspection applications like splice detection, flag detection, and surface defect monitoring — you get vision-like capabilities without the vision system learning curve.

## About Roll-2-Roll Technologies

Roll-2-Roll Technologies designs and manufactures patented fiber-optic web position sensors and advanced web guiding controllers — the precision measurement and control core of modern roll-to-roll manufacturing. Spun out of Oklahoma State University's Web Handling Research Center and trusted by Fortune 500 medical, battery, and nonwovens manufacturers, our patented sensors work without recalibration, with 0.0635 mm resolution and ±0.127 mm repeatability at line speeds up to 760 m/min — typical customer outcomes are 50%+ less downtime and payback under six months. Headquartered in Stillwater, Oklahoma, our team of PhDs, controls engineers, and industry veterans extends the sensor + controller core into complete web guide systems including stepper-motor-based linear actuators (RLA, BLA, LHS).
