Contact lenses and intraocular lenses have exacting requirement for thickness and sag. Bristol Instruments offers real time measurement with sub-micron accuracies. It also has the capability to measure index for exact characterization of material.
- Simultaneous measurement of center thickness and sagittal height
- Non-contact technique means no damage or deformation
- Measurement can be made in a wet cell keeping lens hydrated for accurate thickness
- QC Mode in Opti-Cal software ensures mistake free measurements for engineering, QC and production personnel
Measurement results shown in table below are of a contact lens in a wet cell, displayed in Bristol's Opti-Cal software.
Green boxes show the layers that are within spec.
