A model for the thermal lens which approximates the refractive shape as a parabola is compared with a model which accounts for the aberrant nature of the lens; both models are tested against experimental results. The comparison suggests how the inaccuracies of the parabolic lens model may be corrected while retaining its mathematical simplicity and better predictive power for stronger thermal lenses.
