Illumination engineering books

Post by little sailor
Continues from the previous post -
what about basic books on illumination engineering? Something that would
explain basic designs and their principles so that one could start
experimentin a bit on his own in a sensible way? I have a good general
knowledge of optics, but e.g. a book like John Koshel's illumination
engineering is too advanced for me as a starting point in this field -
as I can't see from that what are the principles that one follows to
start designing illumination optics.
Thanks in advance for any answer to any of my two posts!

I know I'm very late in responding to this, but if the OP is no longer
available, at least my post might be useful to someone else.

I would personally recommend the absolutely excellent book "Introduction
to Nonimaging Optics, 2nd Edition" by Julio Chaves from LPI, Madrid.
More or less the entire field is covered from start to finish, clearly
explained, covering specific examples along with general cases. There's
even a library of very useful geometric optics routines and plane curve
related expressions in the back!

I like some parts of Koshel's book, but other parts are simply too
specific to be especially useful to the "general" nonimaging-optics
reader. Lots of focus on optimisation, as well, which, while relevant to
the daily life of an optical designer, doesn't make especially
interesting or groundbreaking reading. At least in my opinion.

Another book worth mentioning is "Nonimaging Optics", by Winston, Miñano
and Benítez, especially chapter 7 for design problems. However, it
suffers similarly as to Koshel, and perhaps more damningly, there are
errors and oversights - for example, some of the graphs and figures in
that chapter showing the end performance for surfaces tailored according
to the methods shown for specified parameters are actually for
*different surfaces*, and there are some typos in the section on the 3D
point-source tailoring section which make some of the resulting
equations useless (using the same letter but with different accents to
mean totally different quantities is asking for trouble...). So,
basically, start with Chaves.

Hmm Chaves is a bit spendy. Welford and Winston looks more in my price range. :^)

I found a copy for $100ish on ABE, and technical books are
tax-deductible, so it seemed like a good bet.

The edge-ray principle is really pretty. (W&W talks a lot about that.)

We use to use long cones for concentrating FIR light onto a bolometer or other
detector. A grad student then made his parabolic. That's about as much as I know.

We use to use long cones for concentrating FIR light onto a bolometer or other
detector. A grad student then made his parabolic. That's about as much as I know.

The idea is that you only need a sharp image at the edge of the
detector, and don't care too much what happens away from the edge, as
long as no rays are lost. That's why in 1-D you put the focus of the
left-hand parabola at the right-hand edge of the detector, and vice
versa. There's a range of angles over which no rays are lost.

It's more complicated in 2-D on account of skew rays, but you can get
pretty close to 100%. W&W have a lot of discussion and graphs and stuff.

I haven't had the chance to get into it much yet. At a once-over, it
looks pretty good, though it isn't as much fun to read as Welford & Winston.

I know I'm very late in responding to this, but if the OP is no longer
available, at least my post might be useful to someone else.

I am the OP, and I thank you very much for your analysis.

In the meantime I had already "converged" to the book of Chaves, I find
it - up to the pont where i read it, that is the first explanations
about flow lines, detailed and reasonably easy to follow.

I have also read through the book of Koshel and I agree that it is more
of a reference book than a book for learning design techniques (although
I do not remember anymore what I read, it was the impression that I got
at the time). Moreover - I started with Welford and Winston (I do not
know if Winston, Miñano and Benítez is based on that!) I read and
experimented a bit with the edge ray principle, but I wasn't able to
understand what is a flow line and why it is useful from their
explanation; that is when I switched to the book of Chaves.

By the way for a software I bought myself LensLab (the entry level
version of Optica), I find it much fun to work with and - even if I do
not have any other significant experience with optical design programs -
I do have the guess that for learning it is better than standard
programs (which anyway I decided not to buy as I did not want to invest
the couple of thousands Euro for something that I yet don't know where
will go); and the reason is that Mathematica gives one much flexibility
to analyze the system according to one's wishes.
One problem with LensLab is that the intersections with the surfaces are
not always found - I experimented in different ways and at the end for
example I had to give up reproducing a diagram in Welford and Winston,
the one where the rays that hit a CPC are classified according whether
they are transmitted or rejected and for the transmitted ones the nubmer
of reflections is counted. I know that Optica is better on that respect,
but again it is much more expensive.
