You might also consider optical silicone. You can get some pretty amazing undercuts and still get the part off the tool. If not by pulling then by blowing it off with air via a retractable pin.

I switched from Dell workstations to Boxx and now to a Boxx laptop. Support is excellent as is the performance of the software on the machine. If you have the flexibility within your organization and the budget I would suggest taking a look.

Rough thoughts from having built a heliostat from an old Comcast dish to heat my pool:
Q1: Seems you really want to concentrate the energy on as small an area as possible. In order to transfer the heat from the collector to the water either the water will need to dwell a long time or the...
You might try contacting the LCOS for a referral or looking in the Photonics Magazine Buyers Guide for a backlight supplier. Same goes for outsourcing the design if that is where you need to go. The Buyers Guide is available online I believe. Otherwise, Google is your friend.

You can tell as an Admin? He hasn't been logged in since the 2nd. Bummer. Not many optical posts lately.

Without knowing what the OP wanted to do and the actual source it is kind of hard to solve his problem.
Just a thought though, I've have messed around with DLP systems and in the LED based products there is a pair of aspheric lenses immediate to the LED. They are there to collimate the...
Not sure who's system you are using but here's a link to a book on the subject: http://www.kosi.com/Raman_Spectroscopy/books-Handbook.php

Thanks for the links. I had all but the last one (which didn't work but I found a copy with a quick search). The first surface mirrors in the research papers all have significantly higher reflectivity than the machined aluminum that I am measuring in our lab. I'd really like to have a reliable...
I can find a lot of data for first surface thin films from UV to IR including oxidation over time. What I am looking for is the reflectivity over the visible spectrum from 0 to 90 degrees incidence for common Aluminum Alloys such as 2011 and 6061. I can already plug in a number of aluminum...
A quick Google search turned several pdf's of the data sheet which included dimensioned drawings. I would suggest starting there.

The three or four "softwares" I have that are free downloads or that are links to websites are all as you described (standard lens profiles). If this is the one and only time you will ever do a ray trace you might set up an excel spreadsheet and do the calculations. If the project is important...
Whoa! I didn't go as far as to try all the different constructions you did Rob but I did make a quick comparison between a surface created by two formula driven sketchs (one in each axis) and a revolved sketch. I changed the surface from a hyperbolic to a parabolic since SW doesn't have a...
Hey Rob. I've certainly been there with the surface accuracy issues but mostly with optical surfaces. With a machined radius of .5M do you think it will matter? I wouldn't use it (again) for a parabolic reflector for imaging but I've used it for non-imaging systems and it seems to work well...
