2. 2 mjb8482@rit.edu P09701—Corning Tropel LightGage™ Metrology System Background: “Corning’s LightGage ™ system is an advanced, full surface interferometer for measuring flatness, parallelism and depth”

3. 3 mjb8482@rit.edu P09701—Corning Tropel LightGage™ Metrology SystemP09701 (Tunable Laser) + (Infrared Camera) + (Math Algorithms) = In other words:

4. 4 mjb8482@rit.edu P09701—Corning Tropel LightGage™ Metrology System The Problem: The 1 st generation LightGage™ only measures one side of a part… P09701 …Corning Tropel wants it to measure both sides… …but their engineers couldn’t figure out how to do it! SO THEY GAVE IT TO US (Corning is also looking for engineers to hire)

5. 5 mjb8482@rit.edu Our Task: Design, build and test a working prototype of the 2 nd generation LightGage™ system. P09701—Corning Tropel LightGage™ Metrology System Sensor Controller (PC) Source Unit Master System Controller Parts Handling Sensor

6. 6 mjb8482@rit.edu Looks easy, doesn’t it? - Complete vibration isolation - Isolation from ambient temperature changes - Completely automated, motorized - Sensor must move to within < 1mm of top surface of part, every time - Must accurately measure part in under a minute - Anybody can use it P09701—Corning Tropel LightGage™ Metrology System Remember, Corning engineers couldn’t make it work.

7. 7 mjb8482@rit.edu Looking for engineers interested in: - Photonics/optics - Electronics, systems integration - Data acquisition, programming - Thermal analysis - Ergonomics, user interfacing - Mechanical design - Laser! interferometry - Getting a job P09701—Corning Tropel LightGage™ Metrology System
