Welcome Members
Welcome New Members

OSSC welcomes New Individual and Corporate
Members who joined (or rejoined) in the last 60 days.

We value your membership
and appreciate your support!
The Optical Society of Southern California was founded in 1951 to increase and disseminate the knowledge of optics and closely allied sciences and to promote the mutual interests of investigators, organizations, teachers and students in these fields. The Society is a local section of the The Optical Society (OSA) and typically meets on the second Wednesday of each month from October through June.  Most of our meetings are open to the public.  Those interested in promoting our goals are encouraged to apply for either Individual or Corporate Membership.

An Introduction to Spectrally Controlled
Interferometry for the Measurement of Flat and Spherical Optics

Donald (Don) A. Pearson II
Äpre Instruments, Tucson, Arizona
Conventional interferometry is widely used to measure spherical and flat surfaces with nanometer level precision but it is often plagued by back or multiple surface reflections.  At this meeting, a new method of isolating the measurement surface by controlling the spectral properties of the source (Spectrally Controlled Interferometry - SCI) will be described. Using spectral modulation of the interferometer's source enables formation of localized fringes where the optical path difference is non-zero.  As a consequence, it becomes possible to form white-light like fringes in common path interferometers, such as the Fizeau or Twyman-Green.  SCI technology does not require mechanical phase shifting, resulting in simpler instruments and offers the ability to upgrade existing interferometers.  Furthermore, SCI allows absolute measurement of distance, including radius of curvature of lenses, in a single setup with the possibility of improving the throughput and removing some of the pitfalls of inaccurate measurements.

History of the Fundamentals
of Optical Coatings

Angus Macleod
Thin Film Center, Tucson, Arizona
Nowadays the calculation of the properties of an optical coating is a quite easy matter.  We open a computer program, decide on the wavelength, enter the sequence of thicknesses and refractive indices and launch the program.  However, it took us roughly two thousand years to develop the necessary concepts and the story is an integral part of the history of optics itself.  We start with the early Greeks in Alexandria, move to the Islamic scientists who built on their findings, and follow the trail to Europe where the ideas of refractive index, wavelength and interference were finally developed as we know them today.
