Design, Optimization and Characterization of Optical Imaging Systems for Complex Temperature Environment

Abstract

The optical system’s image quality depends on the following parameters, such as temperature, pressure, number of optical components, in-house mounting and shielding of the lens, etc. The optical imaging system is carefully designed and fabricated to the specific environment to ensure good image quality. Normally, the lens element extends or contrasts due to extreme temperature or pressure. The refractive index (dn/dT) and the focal length (F) are also modified because of the various environmental loads on the lens device. This leads to the original picture being defocused. Here, it is planned to design an optical imaging system to stabilize the image quality between the temperatures −40° and +120°. To achieve this, it is used CODE V program in conjunction with the Glass Expert tool. The problem, in this case, is to find the most appropriate optical glass substance for the temperature condition. According to the objectives of this study, it is planned to construct an optical system and analyze its behavior concerning the suitable glass material under various temperature conditions.
