Reliable data. Documented performance.
NIST-traceable (where applicable) optical testing and verification services supported by advanced in-house metrology.
Our services help ensure optical instruments and components perform accurately and consistently against defined acceptance criteria. At Andover Corporation, verification work is supported by the same state-of-the-art in-house testing and measurement infrastructure used to ensure the quality of our optical filters, coatings, and assemblies.
Spectral measurement and verification
High-precision spectrophotometry for transmittance and reflectance verification, including absolute specular reflection capability using a Cary 7000 spectrophotometer.
Interferometry and optical quality verification
Wavefront and surface-quality measurement supported by a Zygo laser interferometer suite and custom interferometry systems used to verify optical performance where imaging quality and alignment are critical.
Environmental testing support
Temperature and humidity testing to confirm performance stability under specified conditions, including temperature cycling capability from -192°C to +500°C and humidity exposure up to 95% RH (as required by the application).
Inspection and dimensional verification
Quality and dimensional checks supported by systems such as Mitutoyo optical comparator equipment and custom inclusion testing equipment for material inspection and verification needs.
Andover's Optical Verification Program
• Instrument verification support (spectral response, baseline performance, repeatability)
• Optical component performance verification (filters and coated optics) against specified criteria
• Measurement under defined operating conditions (temperature/humidity) when relevant
• Documentation and reporting, including digital and/or hardcopy data as required
Reporting, Certificates, and Traceability
Deliverables typically include measured results, parameters, and traceability notes.
Where applicable, results are provided as NIST-traceable. Reports can be provided digitally and/or in hardcopy format based on your documentation needs.
Calibration Filter Sets
Calibration services are ideal for professional verification, application-specific conditions, or formal documentation.
However, Andover also offers standard NTRM (NIST-Traceable Reference Material) calibration filter sets as a product-based option intended for routine user-level checks of spectrophotometer response and stability.
Quality isn't just a metric
- it's our foundation.
