The "optical" production line
| The "optical" production line
1 - DESIGN
Optical calculations made using two software packages: ZEMAX and SOLSTIS.
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.
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,
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,
- Auto collimator,
- MTF test bench,
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)
