| The "optical" production line | |
| 1 - DESIGN Optical calculations made using two software packages: ZEMAX and SOLSTIS. 2- GENERATING The starting point is a block of glass. The generating represents the outlines of the final part: The piece of glass is machined into the desired shape (prism, lenses, inspection window, etc.) with dimensions close to those of the finished part. 3- POLISHING The generated parts are then smoothed before undergoing a traditional polishing that makes them transparent with a very accurate radius. The final inspection is by interferometry or using templates. The quality of polishing is determined by standardized visual inspection. 4 - OPTICAL COATING Three evaporation chambers are used to produce different coatings: metallic, multi-layer anti-reflection, multi-dielectric, resistive, etc. 5 - CENTERING AND EDGING The operation consists of making the optical center coincide with the mechanical center of the lens. 6 - INSPECTION All components are inspected on suitable test benches: - FIZEAU interferometer, - Spectrophotometer, - Auto collimator, - MTF test bench, - etc. 7 - ASSEMBLY After the inspections, the optical components are assembled into the corresponding mechanical systems. The assembled system then undergoes more quality inspections. (FTM test bench, Auto collimator) |
