  • April 2017 Newsletter

    As I explained two months ago about the licensing agreement with Trioptics-USA to manufacture and sell the Point Source Microscope (PSM) and MicroFinish Topographer (MFT), this gives me time to develop new applications for both instruments and to consult on applying those applications. I am pleased to say that the applications spawned by customer inquiries and my own curiosity have led to four papers that will be presented this summer and fall. See the March Newsletter for the venues, titles and abstracts of the papers.

  • Why is optical alignment so important to optical system performance?

    The main reason is that the other two major factors in performance, optical design and optical fabrication, have already been improved to the very limits of what can be accomplished. After spending good money on a near perfect design and fabrication of optical components does it make any sense not to assemble them in perfect alignment?
