Factors That Influence Thermal Focus Shift: A Thin Lens Model
As a supplement to Deriving a Passive Athermalization Figure of Merit for Length Comparison, this video explores the effect of thermal expansion and refractive index on a thin lens' thermal focus shift. Different classes of lens materials are then compared using this simple equation.
