OLIS Circularly Polarized Luminescence Spectrophotometers
Technologically superior, smaller, and less expensive
than choices from Jasco, Applied Photophysics, and Edinburgh Instruments

At the encouragement of Muller, Riehl, and others in the early 2000s, On-Line Instrument Systems (OLIS), Inc.
added circularly polarized luminescence spectrometers to our product line.
Our approach was to develop a novel sample compartment which allowed positioning of the polarization
hardware before the sample for CD and after the sample for CPL. This ‘Polarization Toolbox’ accommodates
both polarized measurement light (CD) and polarized emitted light (CPL) with no hardware additions.
A third model was developed in 2019 for CPL only. This emission-only model has none of the large and
expensive hardware required for circular dichroism. Exactly and only the hardware required for highest
sensitivity CPL is used, resulting in a physically small and very affordable circularly polarized luminescence
spectrometer, the OLIS CPL Solo.
