Contact and Intraocular Lenses

The Thickness Gauge systems from Bristol Instruments quickly and easily measure the center thickness and sag of contact and intraocular lenses. These instruments employ a non-contact optical technique that provides sub-micron accuracy without the risk of damage or deformation. Our gauges also include the ability to measure a lens material’s group index to ensure the most precise characterization.

  • Simultaneous measurement of center thickness and sag
  • Non-contact optical measurement technique will not damage or deform even the softest lenses
  • Capable of measuring hydrated lenses in wet cells and transparent packaging
  • Straightforward operation easily integrates into your production and quality control processes
