Abstract

It was an effective way to keep the pivotal element of the lens under a specific temperature in order to increase the detection sensitivity, so that the thermocurrent caused by thermal radiation of the lens itself could be control under a lower level, But it was difficult to decide which element was the correct one and what was the temperature should be kept. To solve this problem, we, We used LightTools to simulate the cold optical lens deign and established a calculation and analysis method. which can be applied to the analysis of most infrared systems and has universal applicability.
