Athermal Lenses
The need to maintain focus over a wide range of environmental temperatures is essential to system performance, stability, and high quality. Athermalized lenses kept their performance from changing by means of optical passivity, mechanical activity, and mechanical passivity in a large temperature range. Its configuration will auto-adjust itself when placed at different temperatures.
