OptiGauge II

Non-Contact Thickness Measurement Gauge

The OptiGauge® II is a non-contact thickness measurement gauge for companies looking to move away from traditional thickness gauges. Versatile and objective, the low-coherence interferometer leaves no margin for operator error in obtaining non-contact thickness measurements. This user-friendly system delivers reliability and submicron accuracy so vital to today’s most advanced industries. OptiGauge II is successfully used worldwide in Quality, R&D labs, and production floors because it can improve yields, reduce costs, increase quality, and meet compliance requirements.
