Beyond Refraction: Solving Wavefront Distortion and TIR Leakage in High-Precision Prism Assemblies
In the world of high-accuracy metrology and AR/VR waveguides, a prism is often treated as a "set and forget" component. However, as we push toward sub-micron tolerances, engineers are encountering a wall where the physical mounting of the glass actually destroys the optical properties of the substrate.
1. The Mounting Stress Birefringence Crisis
When a prism is integrated into a housing, it is...
