This course provides a structured foundation in optical metrology for precision optics manufacturing. Students learn how to select, operate, and interpret measurements from common shop-floor and laboratory metrology tools, including calipers, micrometers, measuring loupes, height gages, spherometers, air bearing stations, test plates, interferometers, and interferometric microscopes.
By the end of this course, you will be able to:
- Identify common metrology tools used in precision optics manufacturing
- Select appropriate measurement methods based on optical specifications and tolerances
- Measure and interpret diameter, center thickness, sag, radius, wedge, power, irregularity, waviness, and roughness
- Understand the strengths, limitations, and risks of contact and noncontact measurement methods
- Use metrology data to support process control, quality decisions, and continuous improvement
This course is designed for technicians, engineers, and supervisors working in optical fabrication, polishing, inspection, quality, or similar precision manufacturing environments. Prior knowledge of basic optics is helpful but not required.
