    Abstract(s): 

    The visual performance of the common binocular is a surprisingly subtle and interesting topic.  Human vision and optical design interact in a complex way to determine binocular performance, invalidating simple estimates based on magnification.  Selecting the right binocular for amateur astronomy, bird watching, hunting, or even general use requires considering a wide variety of both optical and environmental factors.   Some of the factors that must be considered include illumination levels, transmission, muscular tremble, field of view, and even alignment of the optics.  More detailed aspects of the design are also important; for example, why do low cost binoculars show square exit pupils when the optics are round?  This talk will show why binocular design is a complex problem, and provide guidance for selecting an appropriate binocular.

    Daniel Vukobratovich is a Senior Principal Multi-Disciplinary Engineer at Raytheon Missile Systems in Tucson, Arizona. His primary field of interest is opto-mechanical design.  He coauthored with Paul Yoder an SPIE Field Guide book about binoculars and telescopes, the 4th edition of Opto-mechanical Systems Design, and a college textbook,Fundamentals of Optomechanics.  He authored over 50 papers, including chapters on optomechanics in the IR Handbook and CRC Handbook of Optomechanics.  Daniel Vukobratovich taught optomechanics in 12 different countries, and consulted with over 40 companies.  He is an SPIE member, and Fellow, and is an Adjunct Professor at the College of Optical Sciences, University of Arizona.   He is a founding member of the SPIE working group on opto-mechanics.  He holds multiple international patents and received an IR-100 award for work on metal matrix composite optical materials.  Daniel Vukobratovich led the development of a series of ultra-lightweight telescopes using new materials (metal matrix composites, foam cores) and as well as space telescope systems for the shuttle mission STS-95, Mars Observer, Mars Global Surveyor and FUSE
