I believe its something to do with the opacity of the plastic changing at different temperatures, so at lower temps it is 'more transparent', something to do with the refractive index of the plastic. Therefore there is less distortion of the laser passing through the plastic at lower temps, But I could be wrong, no one seems to agree on this :) Steve
