As she worked through the tutorial, Emma began to feel more comfortable with the software. She learned how to create and edit surfaces, add materials and coatings, and run simulations to analyze her design.
Elias read a paragraph aloud: "Local minima are the trap of the confident designer. The damped least-squares algorithm will find the bottom of the nearest valley, but it cannot see if a deeper valley lies three ranges over. To escape, one must introduce perturbations—hammer the system." zemax user manual
Pro tip: Use the manual's index, not the search bar. Searching for "tolerance" yields 800 hits. The index, however, lists "Tolerance, operands" as page 1,245 – specific and useful. As she worked through the tutorial, Emma began
