A METHOD AND ARRANGEMENT FOR REDUCING THERMAL EFFECTS IN COMPACT ADJUSTABLE OPTICAL LENSES |
摘要 |
<p>The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.</p> |
