Precision Surface and Profile Measurement with Optical Comparators
Streamline dimensional inspection workflows with profile projectors built for accurate, noncontact visual measurement and surface analysis.
Overview
Optical comparators, also known as profile projectors, are precision optical instruments used to inspect the dimensions and geometry of manufactured components without physical contact.
These devices project magnified images of parts onto a screen, allowing for accurate comparison with engineering drawings, overlays, or digital templates. Ideal for both quality assurance and production line checks, optical comparators deliver repeatable measurements for dimensions like length, radius, angles, and edge profiles—critical in sectors that demand high tolerance standards.
Optical Visual Tech provides advanced profile projector solutions designed for modern B2B environments. Serving industries throughout North America, our systems blend traditional optical precision with modern digital capabilities. As a trusted leader headquartered in Vancouver, BC, Optical Visual Tech continues to expand its presence by focusing on reliability, user-centric design, and technical innovation.

Case Studies
Aerospace Component Manufacturer (U.S.)
A leading aerospace parts supplier based in Seattle integrated Optical Visual Tech’s digital optical comparator system to inspect turbine blade geometry. The system improved inspection speed by 45%, enabling fast approval cycles for both prototype and production parts. Integration with CAD and SPC software also enhanced traceability and compliance with AS9100 standards.
Automotive Fastener Facility (U.S.)
A Detroit-based fastener manufacturer deployed our profile projectors across multiple QA stations. Operators used digital overlays and angle comparison tools to measure bolt threads and head radii with sub-millimeter accuracy. Downtime due to measurement errors was reduced by 60%, improving OEE scores significantly.
Precision Medical Devices (Canada)
A Toronto-based manufacturer of surgical implants adopted our FBG-integrated optical comparators to verify micro-grooves on orthopedic devices. With optical magnification and automated measurement recording, the company exceeded CSA and ISO quality standards while reducing inspection cycle time by 30%.
