Development Experience includes:

  • Automated Mach-Zender systems for high volume testing of ophthalmic lenses
  • Low-profile interferometers for testing high-precision aspheric telescope mirrors
  • Non-interferometric Wavefront Sensor systems for high-vibration environments
  • Low coherence systems for dimensional characterization
  • Scientific Camera-based applications for dimensional analyses
  • Low coherence interferometers for systems with multiple, closely spaced surfaces
  • Low signal interferometers to characterize immersed optical surfaces
  • Eye-safe Twyman-Green interferometers to characterize the human tear film

It all begins with Signal Creation and Signal Capture. Not all test systems are created equal.  Each has strengths, and each has vulnerabilities. The team has experience with virtually all variants.  Optical Systems Engineering Group carefully:

  • Analyzes the components or systems which need to be characterized
  • Identifies appropriate configuration options
  • Performs full trade studies to determine the configuration best suited for the customer’s technical requirements, the customer’s test staff, and the customer’s future product plans.

Systems may also include:

  • Self-contained environmental controls
  • Equilibration mechanisms
  • Calibration standards
  • Software interfaces to existing laboratory management software.

Next is Signal Extraction, a crucial step in any optical measurement.  Test apertures must be applied properly, scaling and magnifications must be taken into account, and rigorous algorithms, such as phase un-wrapping in the case of interferometers, applied.  Each critical factor is painstakingly analyzed and applied in robust algorithms to produce an optical signal that can be trusted.  Commercial applications may be modified by Optical Systems Engineering Group or fully customized software can be developed, depending on the application and the customer's requirements.

Signal Analysis is the fourth step and is as critical to success as any.  Data is only useful if it supplies a customer with insights into process and product quality.  The team can provide:

  • Data extracts in standardized form - Zernike, Seidel, Ophthalmic
  • 3-D wavefront maps
  • As-manufactured wavefronts compared to as-designed wavefronts
  • Full Dimensional Characterization
  • Power Profiles
  • Lot Analyses
  • Customized Applications

Any or all may be automated for production efficiency.

Advanced Analytics combines predictive analytics, simulation, and optimization on structured and unstructured data to provide insights into:

  • Manufacturing processes
  • Customer satisfaction
  • Product development
  • Product quality. 

Techniques include linear, non-linear and logistic regression, survival analysis, text analytics, website analytics, and machine learning.
