For Your Information Optics Letters is a new journal devoted to dissemination of information on important results in all branches of optics. T h e journal will be published by the Optical Society of America as a companion journal to both Applied Optics and the Journal of the Optical Society of America. It will be sent free to all members of the Society and for the first six months will be distributed free to all nonmember subscribers to the two Society journals. T h e editorial office will begin to process manuscripts in March 1977 for the first issue (Volume 1, Number 1) which is scheduled to appear on July 1, 1977. A firm limit of three printed pages and voluntary page charges will be enforced. T h e editor is R. W. Terhune, Research Laboratories, Ford Motor Co., P.O. Box 2053, Dearborn, Mich. 48121 (313-322-6785).
FLASH PHOTOLYSIS SYSTEM FOR RESEARCH For Flash Photolysis Spectroscopy and Kenetic Spectrophotometry.
Fluidized baths are excellent for laboratory tests n
Model 720C Model-720C is the most significant advancement in Flash Photolysis instrumentation to date.
Compare with An oil bath: fluidized bath is safe, works over wider temperature, eliminates fumes/ odor and need for expensive oil
Model-720C features: Fast extinguishing flashtubes * ultrastable kenetic analyzing source * optional 10 nanosecond spectro flash.
FLASH PHOTOLYSIS SYSTEM FOR TEACHING
An oven: fluidized bath provides better temperature uniformity, more rapid heating, improved accessibility
A teaching system for Flash Photolysis Spectroscopy and Kenetic Spectrophotometry.
A heating mantle: fluidized bath accepts wide variety of lab vessels, gives higher heat transfer rates
Model 725 Model-725 is a safe, low-priced, easy to use instrument for undergraduate teaching in chemistry, physics, biology and materials science. It is an effective system for studying lifetimes and spectra of intermediates with lifetimes as short as 250 microseconds. data call or
