Tolerancing

This section covers the tolerancing capabilities of Optiland. Tolerancing is used to determine acceptable limits of variation in the manufacturing of optical components and systems. These variations can arise due to imperfections in the manufacturing process, such as slight deviations in the shape or alignment of optical elements. Tolerancing ensures that despite these imperfections, the performance of an optical system will still fall within an acceptable range.

In Optiland, tolerancing is performed via sensitivity analysis or Monte Carlo simulations.

For tolerancing of multilayer thin film coatings specifically, see the Thin Film module.

Tolerancing in Optiland requires 4 key components:

  1. Optic - the optical system to be analyzed.

  2. Operands - the metrics which are assessed e.g., wavefront error.

  3. Perturbations - the variations applied to the optic or a surface of an optic e.g., surface tilt.

  4. Compensators - an optional parameter of the optical system that can be adjusted to counteract the effects of a perturbation.
