Dear Colleagues, I have a question for you. A novel optical coherence tomographic (OCT) system use the axicon to focus a parallel beam into long focus depth as well as high confined lateral spot. The axicon lens, also known as conical lens or rotationally symmetric prism is one of the possible optical components that can be used to focus a parallel beam into long focus depth (see, for example http://www.sciner.com/Opticsland/axicon.htm) My question is: what other optical components, may be diffractive (binary) optics, can be used for the same purpose? Thank you. Dr. Sergey Egorov Del Mar Ventures __________________________________________________ Do You Yahoo!? Send FREE Valentine eCards with Yahoo! Greetings! http://greetings.yahoo.com
