Sorry....Bud No Sarcasm intended. 25 years in the laser industry dealing with these. They are not easy to develop. Just thought I would save you time......that's all. Good Luck

MARKY: I already know that these arms exist in the market and they cost a fortune ($10,000-13,000). The cost is the only reason why Iam trying to design and manufacture it which would be around $1500 if done in-house. While I would like to thank you for the reply, I emphasize that I really do NOT appreciate any sarcasm! F. Ishak

It seems to me that you may re-inventing the wheel. There are dozens of companies that make these arms. www(DOT)optotek.si/index.php?id=50 www(DOT)lasermech.com/industrial.shtm www(DOT)oxid.com/ These are just a few places.......I think a google search should find several more Good Luck Marky No commercial direct links please - Admin Modified by Administrator at Thu, May 25, 2006, 15:53:50

Attached is a quick sketch of how the system may look like. Basically, 2 mirrors mounted @ 45 degrees to the optical axis (which is concentric with the tubes). the laser beam will enter thru the first tube, reflect @ 45 degrees at the first mirror to travel and hit the second mirror and bend 45 degrees again to exit at the second tube. Iam concerned with quality and component design of the joing (to allow rotation around the optical axis) as any misalignment even in the order of +- 0.001 would shift the laser beam away from the optical axis and will require hours of adjustment. hence I believe I need precision components (bushings or bearings) to minimize axial or radial shift of joints. I hope I am clear about my objective. Thanks for the help   Modified by maceng at Mon, May 22, 2006, 22:23:36
