Large Curing Tips vs. Small Curing Tips

 

Return to Optilux Index

Tip size is crucial to the intensity of a curing light. Intensity is the power divided by the area. Since area is proportional to the square of the the radius, a small change in radius makes a big change in intensity.

Example: 300 mW of power delivered through an 8 mm or 11 mm tip.

8 mm tip
11 mm tip
radius = 4 mm
radius = 5.5 mm
area = 0.50 cm2
area = 0.95 cm2
intensity = 600 mw/cm2
intensity = 316 mw/cm2

In general, small tips have higher intensity than large tips on a given light.
