Reviewer 2 Report
In this paper, the integrated optomechanical analysis and optimization are proposed for the primary mirror assembly of the aerial optoelectronic sensor. In the optimization process, shape error of the mirror is set as the objective function. The results demonstrate that the size parameters have significant effect on the optical performance. The fundamental frequency of the primary mirror decreases from 594.1 Hz to 203.1 Hz. Both the optical performance and thermal adaptability of the camera have been enhanced after optimization. However, there are some questions:
For the optical mechanical system, its performance depends not only on the performance of its primary mirror under various conditions, but also on other components such as secondary mirror and so on. This paper mainly optimizes the main mirror assembly. To better show the thermal adaptability of the whole system under different temperatures? can the system be optimized as a whole?
In this paper, the imaging performance of the optimized system is represented by MTF with 0 field angle. When the optical system is used in a aerial optoelectronic sensor camera, can you specify the FOV of the camera? And how does the optimized system perform in other FOVs?
“30oC uniform temperature decrease” is frequently mentioned in this paper. How is it embodied in the optimization? What is the temperature range it refers to?

Reviewer 3 Report
This manuscript combined and studied together the optimization design of the mirror and its supporting structure. High thermal deformation resistance of the primary mirror of aerial optoelectronic sensor is considered for better adaptation in the low or high temperature working environment. A detailed size optimization of the primary mirror and the flexure is conducted together to optimize their dimension parameters. It is practical. However, I think this manuscript is an application-oriented paper. There are not experimental or theoretical novelty when compared to existing literature. Its contribution is not enough. In the optimization processing, multi-merits function and boundary limits are necessary and basic to perform this kind of work. The authors must clarify which contributions were done in this paper and compared with other optimization processing, not limited in the specific mounting primary mirror.

Reviewer 4 Report
This review covers design and optimization for imaging optics with reduced sensitivity to temperature change. This topic is of particularly high technical relevance for precision opto-mechanis. Theoretical modeling and optimization approaches (material analysis and mechanics of materials) are well organized and presented. In addition, experimental data verified the optimization results well. It will be helpful for researchers interested in optimization for optics design in large temperature change environment. There are several issues to be corrected and the paper needs improvement before being publishable.
For example,
- Overall, the analysis is done with a steady state condition. Can you provide any analysis or discussion on transient conditions?
- A scale bar in the figures would be helpful to confirm the size of parts.
- Line 179: fem ->FEM
- Line 196: the optima [].??
- Line 261: In, Figure 5 Zernike coefficients are given, however please provide the definition of Zernike polynomials and its coefficients
- Line 277: Figure 5 (6), ??
- Line 367: “… obtained by the visible system is shown in Figure 13 （b）. It can be seen that the smallest discernible stripe is the 16th group under low temperature condition. The result demonstrates that although the image quality of the camera degrades, it still meet the requirements of the index.” -> Could you specify the difference and similarity in Fig 13 based on the analysis? It is difficult to pick pixels to be compared in Fig. 13.
