Webinar: The Autostigmatic Microscope and Its Uses

This webinar with Robert Parks is presented by the OSA Systems and Instrumentation Technical Group.

Topics discussed include the evolution of the classical autostigmatic microscope (ASM) into an all-purpose optical alignment tool whose use has been described in over 60 optical engineering papers that illustrate real-world systems applications.

The evolution that led to the current instrument, the Point Source Microscope or PSM, is due to a convergence in technologies of solid state light sources, digital cameras, modest cost computers and software to operate these devices to create a small, lightweight and ergonomic optical test instrument with many functions.

What You Will Learn in the Webinar:

  • Viewers will learn the fundamentals of autostigmatic microscopes and how they are used to find the radius of curvature of optical surfaces. This background into fundamentals leads to discussing the use of the ASM in practical alignment situations.
  • Viewers will be presented with a variety of applications of the ASM to the alignment of optical systems, particularly applications that include aspheres and folded optics to give an appreciation for the capabilities of this technology.

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.
