Loop Overview
For optimal results, consistent light delivery is crucial. However, achieving perfect hand positioning and distance with a traditional curing light can be challenging. Loop takes the guesswork out of light curing. It’s the only curing light with real-time feedback that automatically adjusts power to deliver the precise energy dose required for an ideal cure, every single time.
Operational Tips
These functions may differ slightly from other curing lights but are critical for delivering consistent energy as set, regardless of distance or angle. Traditional curing lights may vary by up to 50%, even when positioned directly over the target.
Multi-Function Buttons
Functions activate on button release, not on press. To start a cure, press and release the start/stop button.
Closed-Loop Activation
In Closed-Loop mode, the light needs to be within 3mm of the target to begin curing, with a short flicker before the cure starts.
Closed-Loop Timeout
If the light moves more than 10mm from the target, it will blink to indicate a misalignment. After 3 seconds out of range, it will automatically time out.

Precision Light Delivery
Loop is designed to deliver light only when it is properly aligned with the tooth. By pausing the curing process if the lens drifts too far from the target or is not
correctly positioned before starting, Loop ensures the precise dose of light energy is delivered exactly where it is needed, preventing under-cured materials.

Closed-Loop Technology
This system dynamically adjusts light output based on distance and angle, ensuring consistent energy delivery to the tooth. If the light moves too far, it pauses until properly aligned.

Automatic Self-Calibration
The dual calibration system includes daily checks to account for lens debris and monthly verifications to maintain original specifications, ensuring optimal performance.
