Optomechanical Design Of The Gun Scope Optics Using An Uncooled LWIR Thermal Imaging Sensor With A Precise Image Focusing Mechanism

A well-designed optical system for a gun scope [1] needed an optomechanical enclosure to accommodate all the optical and electronic components for its required functionality and use. For this purpose, a design process was initiated considering all the optical and mechanical performance requirements of the intended product, to formulate a mechanical housing. A certain set of design steps was followed, conforming adherence to the required features and safe performance of the gun scope optics. Gun scopes equipped with uncooled thermal imaging sensors operating in the LWIR (Long-Wave Infrared) range of 8–12 μm are advanced optical devices essential for military and law enforcement applications. These forces operate in extreme environments, from freezing mountain ranges to scorching deserts, requiring equipment that performs reliably under all conditions [2]. Optomechanical design process is quite different and challenging as compared to other conventional mechanical design processes. It involves a serious consideration of the factors, whose negligence could result in total catastrophic failure or at least a major deviation from the intended results. Use of very fine geometric tolerances and careful consideration of mechanical properties of different materials used, could only guarantee a successful designed product. After completing a precised optical design and analysis process, its needed to formulate a suitable mechanical housing for lenses and electronics for the required functionality of the product. In this paper, all major optomechanical design steps and design considerations to be cared off, are discussed which are followed to make a successful product, complying all the requirements
