Contact and Intraocular Lenses

The manufacture of contact and intraocular lenses has exacting dimensional requirements, including center thickness and sagitta. Bristol Instruments offers non-contact, real-time measurement of lenses with sub-micron accuracy. Our thickness gauges also include the capability to measure a material’s group index for exact characterization.
