OSA Rochester Section
 

The Rochester Section of the Optical Society of America is a group of people in the optics industry interested in promoting the knowledge of optics for the local community.

 

  The 100th Anniversary of the OSA Rochester Section
It was Novemeber 18th, 1915 when nine Rochester scientists met at the University of Rochester: four from Eastman Koak Co., four from Bausch & Lomb, and one from the University
 
 
 
 

How to Measure a Bone's Chemical Composition and Mechanical Strength Using Nothing but Light:

Transcutaneous Raman Spectroscopy of Mouse Legs

                       

 

Speaker: Andrew Berger

                         

Human bone diseases are often studied using animal models.  Although mechanical tests can measure the strength of bones by breaking them, it is sometimes desirable to study how an animal’s bone changes over time, which requires noninvasive diagnostics.  Unlike X-ray techniques that probe structure, Raman spectroscopy offers a chemically-specific approach.  Our group has acquired Raman spectra of mouse tibia bones, both ex vivo (isolated) and through the overlying soft tissue of intact legs.  Determining a bone’s spectral contribution to a transcutaneous measurement requires careful processing, particularly because Type I collagen appears in both bone and soft tissue.  In this talk, I will describe our experimental and computational methods of dealing with this challenge.  I will also report that Raman spectra can detect changes in bone mechanical strength that correlate both with disease and with a steroid treatment regimen.

 

Enjoy this talk on Tuesday, January 26th at 7PM.

  Optics Suitcase Demo Contest! 

Up to $500 in prizes for a new optics suitcase demonstration

The optics suitcase project, started here in Rochester, NY, has delivered over one thousand hands on demo kits to students around the world and represents a significant outreach effort to the entire optics community.
 
OSA Rochester Section is leading the development of new demos or "theme packets" for the suitcase, and we want to go get the whole community involved. Download the contest guidelines for a complete list of requirements.

Educational Activities

The Rochester Section is active in the support of optics education in area schools. The Rochester Section developed its Optics Suitcase in 1999. The Optics Suitcase is an innovative, interactive presentation package designed to introduce middle school students to many of the concepts of optics as well as other sciences.

Information on Joining

For information on how to join, please see our new membership form online. We still support both online and traditional postal membership renewal methods. Miscellaneous questions can be answered by our secretary
