  • NEW Instructions for Using CaliBall

    Using the CaliBallTM to calibrate interferometer transmission or reference spheres using the random ball test is almost fool proof.

    However, observing a few simple precautions will improve the results of the calibration.

  • 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.

Case Studies & Testimonials

Why is proper alignment so important?

Here is a case of a very happy customer due to better optics.

A few days ago an astronomer friend of mine commented that he had gotten the optics of his telescope improved and the improvement reduced the time it took to get data by a factor of 3. For an astronomer this is a dramatic improvement since observing time on large telescopes can cost thousands of dollars an hour.

My friend did not say how the optics had been improved, but the important point is that better optics, whether due to figure errors, mounting or alignment mean more productive optics. I generally think of better optics as a better product leaving the manufacturing facility without thinking about how much the better optics mean to the productivity of the customer.
