Optical Metrology Services

The extensive and diversified background of the Opto-Cal staff in optical radiation measurements, combined with fully equipped laboratories, allows us to provide a variety of measurement services. Typically these services are used by customers needing qualification of electro-optical components, companies which have only infrequent needs for optical measurements, companies requiring an independent laboratory evaluation of a product and those not possessing the facilities, staff or expensive equipment required for testing.  ALL measurements are N.I.S.T. traceable, in compliance with generally accepted industry practice or can be traced to naturally occurring physical constants or phenomena. Opto-Cal has been a leader in optical metrology for over 30 years, offering an immense number of options to meet your calibration needs.  Collectively, our Senior Metrologists have compiled over 100 years of experience in the field of optical metrology.  We pride ourselves on the level of customer service we provide, a record unmatched in the industry.
