Thermal Analysis in Zemax OPTI 521 Optomechanics Tutorial Isaac Trumper What is a thermal analysis? • Optical systems are used in a variety of environments, so we model the effects due to the change in temperature, pressure, etc. • Different applications will have different requirements for the range of parameters that the lens needs to operate over. • Military applications typically require ± 50 °C As temperature changes… • Materials expand or contract as a function of temperature, which will
