Abstract
A method of predicting thermally induced aberrations of a projection system for projecting a radiation beam, the method comprising: calculating a change in temperature of the projection system from a power of the radiation beam output from the projection system using a dynamic linear function; and calculating the thermally induced aberrations from the calculated change in temperature using a static non-linear function.
