We analyze recent experiments on measuring the thermal Casimir force with
account of possible background effects. Special attention is paid to the
validity of the proximity force approximation (PFA) used in the comparison
between the experimental data and computational results in experiments
employing a sphere-plate geometry. The PFA results are compared with the exact
results where they are available. The possibility to use fitting procedures in
theory-experiment comparison is discussed. On this basis we reconsider
experiments exploiting spherical lenses of centimeter-size radii.
