Can you provide test reports for your optical glass products?

Update Time:2026/4/28
Yes, at Felix Glass, we can provide detailed test reports for all BK7 and K9 optical glass products, giving you full visibility into the quality and performance of your order.

Our test reports include comprehensive information about the parts, including dimensional specifications, surface quality inspection results, and optical performance test data.
For standard optical glass parts, we provide a basic test report that includes dimensional verification, surface roughness measurement, and visible light transmittance testing.
For custom or high-precision parts, we can provide more detailed reports that include additional test data such as flatness, parallelism, coating thickness, and environmental resistance.

For coated optical glass parts, we provide specific coating test reports that include transmittance and reflectance data across the target wavelength range, coating thickness uniformity, and adhesion test results. These reports verify that the coating meets the specified requirements and will perform as expected in your application.

All test reports are based on actual measurements taken during our quality control process using calibrated testing equipment such as spectrophotometers, interferometers, and coordinate measuring machines. The reports are signed and dated by our quality team, and include information about the test methods used and the applicable standards.

If you have specific test requirements or need to comply with industry or customer standards, we can customize the test reports to include the required information.
Providing test reports is part of our commitment to transparency and quality assurance. We want our customers to have full confidence in the quality and performance of our optical glass parts, and our detailed test reports help to achieve that.

If you need test reports for your optical glass order, please let us know when placing your order, and our team will provide you with the required documentation.
