Welcome Members
Welcome New Members

OSSC welcomes 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.

STEM & The Arts Career Showcase
Thanks to everyone who helped!!
Vital Link STEM Event Photo
The STEM & the Arts Career Showcase is an annual three-day event held at the OC Fair and Event Center that gives students the opportunity to explore career pathways in STEM fields.  The program brings together industry professionals, educators, and college representatives that provide students the opportunity to explore their future.  The program includes student competitions and displays, industry demonstrations, career exploration exhibits, industry speakers, a job recruitment area, live entertainment, and more!  The program reaches over 6,000 targeted students, parents and their families.
Thanks Justin Francis, Bo Wang & Donn Silberman for organizing and volunteering at the event.


Recent VOSA Meeting

8 May 2018
Ray Tracing Rain Drops
Elliot Burke
VOSA 8 May 2018 Image
Abstract:  This talk is intended to add some footnotes to what David Lynch talked about in April.  In particular, computation of the optics of water droplets.  This will be treated with ray tracing, which can simulate the effects of water droplets, non-round water droplets, ice, dispersion, polarization, and diffraction.  There are many complex phenomena which arise from such a simple system and I intend to track down as many of them as I can find.  Suggestions will be welcome.
Venue:  Advanced Spectral Technology, Inc.

Applications of Short Coherence Sources in Fizeau Interferometry

Dr. Michael North Morris picture
Abstract:  Most Fizeau interferometers use laser sources with many meters of coherence to ensure high contrast fringes are produced regardless of the position of the test article.  The independence of the fringe contrast from test part position is admittedly very convenient.  However, using a short coherence source with internal path matching opens up applications that are not possible with the longer coherence source.  These applications include isolating the surfaces when measuring plane parallel optics, facilitating test and reference beam separation for vibration immune interferometry, and streamlining radius of curvature measurements by moving the position detection internal to the interferometer.  This presentation will cover the theory behind each of the applications and present practical results from commercial implementations.  Of particular interest will be the surface isolation as applied to a large 24-inch aperture interferometer and radius of curvature measurements in a production environment.

Challenges and Opportunities in Asphere and Freeform Metrology
Mahr 180509 Asphere Graphics
Dr. Brent Bergner,
Senior Optical Engineer, Mahr
Abstract:  Aspheric and freeform surfaces can be a useful addition to the optical designer’s toolbox.  The additional degrees of freedom allow for a reduction in the number of surfaces, making systems lighter, cheaper, and more compact.  New technologies such as MRF, slow tool servo diamond turning, and optimized molding and replication techniques have expanded the range of their practical applications.  However, aspheric and freeform surfaces can still be difficult and expensive to measure.  In this presentation, we survey the various methods for measuring these surfaces and examine some of the sources of error, limitations, and other gothchas for each of the techniques.  With that prospective we then look at recent advances and potential paths forward for improving the accuracy, speed, and flexibility of aspheric and freeform metrology.

Laser Cooling & Trapping on ISS
Dr. Robert Thompson
Jet Propulsion Laboratory
California Institute of Technology
Microgravity offers a wealth of advantages for studies of ultra-cold atomic gases and their applications.  These include the ability to achieve exceptionally low temperatures via expansion into very weak traps, which don’t need to be supported against gravity and the ability to achieve very long interaction times with samples that have been released from traps.  The Cold Atom Laboratory (CAL) will be a flexible, multi-user ultra-cold atom facility that will enable the precise study of quantum gases at effective temperatures well below the coldest achievable on Earth.  CAL will launch to the International Space Station in early 2018, giving scientists a unique window into the quantum world.
