Optical design
« on: 08:10:12, 09 July, 2011 »
Hi all,
If this is in the wrong place I appologise.

As a side hobby I would like to get to grips with the science behind optical design and as such I'm trying to find infromation that is not too technical as a starter. I have briefly trawled the net and everything found so far seems to assume some kind of science degree is held. My first thought was towards a possible software package that lens parameters could be entered into and maybe a graphical representation shown of the results.

Has anybody got any suggestions.

Google OLSO - this is an optical design package...
but you'll still need some basic understanding of the terminology - refractive index, etc

Thanks Merlin, but I think that $1250 is out of my range for hobby use. The package does look good though.

Tony - OSLO65 EDU is free. It limits the number of surfaces to 10 but you can start to explore with it. Indeed I use it for my spectroscope designs. It is a bit had to get your head round but it has expample lens that you can look at which is how I find out what to do.
