How to perform stray light analysis

It is often very convenient to analyze rays with specific qualities in order to assess the design and make adjustments to improve performance. The Filter string is a convenient tool in OpticStudio which allows the definition of a test that rays must pass before they are drawn or displayed. Filter strings can be used to perform a full optomechanical assessment of stray light, and will consider reflections, scattering, and coatings to both mechanical and optical components.
