Metrology

METROLOGY is a serious matter.

At Hyperion, we believe in quantitative science. Since its founding in 2008, Hyperion has continued to invest in metrology capabilities. Our QC department is equipped to inspect almost every precision optical specification. From optical component to complex lens assemblies, Hyperion employs quantitative measuring devices along every step of production to monitor and safeguard quality.

100% Inspection = Guaranteed satisfaction

Detailed inspection reports signed off by our QA managers will accompany every product shipment. Dimensional measurements, ZYGO interferometry reports, and actual coating curves are standard items in a given inspection report. Every specification on print is 100% tested before shipment to ensure what you receive will meet or surpass your quality expectations. Interested in seeing what is included in our standard QA report? Contact us to request for a sample inspection report.

In-House Metrology

Hyperion offers a range of comprehensive metrology capabilities in standard QA procedure. Customized testing is available upon request, such as material index, dispersion testing, thermal testing, and other application-based tests. Our QA engineering team can customize an inspection plan for your specialized application needs.

7. Mechanical Measurement

Hyperion employs a range of mechanical inspection tools such as dial gauge, vernier calipers, micrometer to accurately verify dimensional measurements of our optics. We can test dimensions between 0-300mm to an accuracy of +/-3μm. All the devices are calibrated in accordance with ISO: 9001:2015 and Chinese GB standard.

The below chart illustrates the typical inspection protocols involved with each lens component and assembly fabrication:

Hyperion’s QA engineering team goes above and beyond to proactively calculate every lens focal length to verify the product before shipment during final QA process. Each lens’ focal length will be recorded on the inspection report.
