Call us with your questions today!
  • NO: The RSM does not use multiple array detectors. This is a double grating scanning monochromator which is 7,500 fold faster than conventional dual beam systems and 100 times more photometrically sensitive than most diode array detectors.
  • YES: The RSM is 100% new. We are not making new technology spectrophotometers from 1960's models!
  • YES: We continue to support older instruments. We call this our 'vintage' line to distinguish it from our RSM line.
  • NO: We do not offer software on Macs. Years ago, we started with MS-DOS machines because the data collection hardware (A/D converters) were available for MS-DOS models. We have stayed with DOS systems because they are faster, less expensive, and available everywhere. We offer out strong opinion: the computer is a necessary component with two jobs-- running the data collection card (the A/D) and running the software. For now, we recommend you think of the computer as we do: a necessary component with two jobs; hold the data collection card and run the software.
  • YES: All Olis products delivered in late 2002 and afterwards are installed with Windows NT/2000™ compatible Olis software.
  • YES: All Olis instruments circa 1983 to 2001 can be changed to run under the Olis SpectralWorks/GlobalWorks Windows™ compatibility.
  • YES: We are a small American business, 'family owned and operated.' Did you know that 75% of businesses are family owned in America?
  • YES: You might never have heard of us. But is that any reason not to contact us now?
  • "How did a little company in Bogart, Georgia, make such a dramatic advance in optical spectrophotometry?"

    The answer is simple: our company founder, Dr. Richard J. DeSa and perfect timing. A biochemist and inventor whose often stated philosophy is "Everything Ought to be Improved," Dr. DeSa invented a better monochromator at exactly the best time in history. If he had invented this monochromator before sufficiently fast computers, PMTs, and electronics were around, the monochromator would have been a novelty. And, without the invention of factor analysis and singular value composition, the users of this monochromator would have been faced with analyzing tens and hundreds of thousands of data points with conventional methodology. As it happened, the hardware and software power were in mature states exactly when we needed them to make the DeSa monochromator a success.
