The keyword “STOP” refers to an investigation of structural, thermal, and optical performance. This type of analysis entails assessing and optimizing the performance of a system that combines optical, thermal, and mechanical components. It is especially important in the design and analysis of systems where optical parts are subjected to variable temperatures and mechanical stresses, such as lenses, mirrors, telescopes, lasers, and so on.

STOP stands for Structural Thermal Optical Performance:

• Structural (S): This aspect involves analyzing the mechanical or structural integrity of the system. It entails assessing how the system’s various parts react to stresses such as vibrations and mechanical loads. This is necessary to ensure that the system can endure any environmental conditions that may arise.

• Thermal (T):  Thermal analysis is concerned with understanding and managing heat distribution within a system. Temperature changes in opto-thermomechanical systems can have an impact on the performance of optical components. Thermal analysis assists designers in ensuring that the system remains within permissible temperature ranges in order to preserve optical performance and avoid damage.

• Optical (O): Evaluating the optical elements in the system in response to mechanical loads and temperature variations is part of the optical performance aspect. In order to make that the system satisfies its performance criteria under various circumstances, this entails examining indicators such as aberrations, image distortions, and other optical characteristics.

• Performance (P): This often refers to the system’s total performance, taking into account both the optical and mechanical aspects. The goal is to optimize the design and settings so that the intended performance may be achieved in real-world operating situations.
