Lens design and website design
Lens design is the art and science of designing optical systems - the lens in your camera is a product of this craft. So what is the link between that esoteric subject and website design? Why devote a whole section of this site to mini-essays on this highly mathematical enterprise?
Well - without lens design this world would be completely different. For a start there would be:
- no cameras
- no telescopes
- no microscopes
- no endoscopes
- no photocopiers
Less obviously, there would be:
- no computers [my first essay discusses this modest assertion]
- no internet
Hence no websites and no website designers - a clear link I believe! To my mind a technology which has enabled all this deserves some note. But ask yourself, have you ever met a lens designer - do you know what they do?
I have a personal interest as well - having been developing lens design software for many years now [you can see some examples at this site].
So in these essays, I will try to explain, in non technical terms, some of the importance of lens design. BTW, my notes will be refined as time goes along - unlike a blog entry, so don't be suprised if the more recent entries seem unpolished!

Glass is glass?
Lenses are made of optical quality glass [or some other transparent material]. Amazingly, optical glasses have a huge range of properties - some can be dipped in boiling acid, while others will stain at a touch of your hand. The right choice is crucial for a good lens.
