A: Phase 1: Optical Definition and Design
1: Determine the optical band
2: Determine core performance parameters(focal length, field of view, etc.)
3: Select initial structure
4: Aberration optimization and optical design

Phase 2: Performance Validation and Production Preparation
5: Comprehensive image quality evaluation
6: Tolerance analysis and specification
7: Drawing output

Phase 3: Prototyping and Mass Production
8: Prototype Production
9: Testing and Iterative Optimization
10: Formal Mass Production

A: During the design phase, we primarily use Zemax for optical design and simulation, alongside SolidWorks/Siemens NX (UG) software for mechanical design and system
integration.
