The discussion centers around the search for quality undergraduate optics textbooks. Hecht is mentioned as a readable option for modern optics but criticized for lacking depth as a reference. Born and Wolf is noted for its complexity, often requiring supplementary resources for understanding. Jenkins and White, despite being outdated, remain popular, while Pedrotti and Pedrotti provide a simpler alternative to Born and Wolf. Modern Optical Engineering and Modern Lens Design are seen as lacking in detail for practical optical design. The Military Handbook of Optical Design is highlighted as a free, albeit dense, resource. Stone's "Radiation and Optics" is out of print but may be available in libraries. Overall, opinions on Hecht vary, with some finding it lacking in rigor compared to other texts, particularly in geometric optics, which some argue is less relevant due to software advancements.
