Olis

Olis, Inc.  originally On-Line Instrument Systems, Inc.  started in 1974 by three young biochemists with expertise in optics, electronics, and the young field of computer programming. Today, this privately held American company continues to serve the biophysical, biochemical, and bioenergetics fields with absorbance, fluorescence, and circular dichroism spectroscopy for sophisticated research and routine measurements.

Our highly innovative bent has spawned specialized and exclusive instruments. We offer the only circular dichroism spectrometer in the world capable of operating without a lock-in amplifier. We hold the patent on a rapid-scanning monochromator which supports collection of 1,000 scans per second. In 2006, we introduced a compact, fast, and precise line of UV/Vis and NIR Hummingbird monochromators, around which modular single or multiple purpose spectrophotometers are built. Among these is an affordable small fluorometer which supports acquisition rates in the second, millisecond, and microsecond time regimes. In 2007, we introduced spectacularly sensitive NIR CD, CPL, and Polarization of Fluorescence spectrophotometers, which utilize liquid crystal variable retardance in place of piezo-elastic modulators.
