Motivation and Introduction to Lens Design
As an optical lens designer, I used to believe, "I can achieve the required performance with software, but I need to understand the underlying principles."
In today's fast-paced world, we must rapidly deliver high-performance (though not always high quality) lens designs. The complexity of non-intuitive lens systems, such as aspherical and off-axis lenses, is common now. Software like Zemax and CodeV has become essential tools.
I occasionally catch myself entering parameters with the push of a button, resulting in the desired performance. Yet, I stop short of relying entirely on software, as I view myself as a scientist and researcher, genuinely intrigued by the lens design process. I found that merely producing machine-like lens designs made me struggle with designing varied systems when needed.
This realization led me back to studying. Numerous books on optics, system design, manufacturing technology, and lens design methods exist to help deepen my understanding.
Consequently, I dedicated time to connecting the dots, integrating theoretical knowledge into a cohesive understanding of lens design, ultimately compiling this guide, which I wish I had at my fingertips during my early career or when learning about lens design.

Understanding Optical Lens Design
Optical lens design comprises several disciplines, one of which involves imaging lenses. The project's specifications dictate the desired results, resulting in varying similarities and differences among lens designs, which can be categorized as Lens Design Forms. These forms consist of combinations of positive and negative optical powers, characterized by their configurations, such as spacing, lens numbers, materials, and optical power. Understanding the historical context of lens design highlights how various needs and the technology of different eras led to the advancement of lens designers' capabilities.
Each section of this Guide will typically cover:
- Historical background and context of each lens design topic
- Essentials for lens design
- Connections to other lens design knowledge
- Helpful tips and tricks for effective lens design
- Real-world examples with illustrations where applicable

On a foundational level, understanding lens design forms effectively enables us to analyze the various properties of a specific lens and ascertain if its performance meets quality standards, and whether the ray paths exhibit the desired behavior.
Critical properties include lens diagrams, glass types used, and ray behavior through the lens system.
This understanding affords a lens designer the ability to evaluate lens designs intuitively, distinguishing the advantages and pitfalls of a given lens.
With experience, confidence in one's pattern recognition increases, empowering lens designers to decipher complex lens surfaces and achieve superior lens design performance.
