The Olis DSM CDs provide higher sensitivity, shorter collection times, and superior data analysis facilities when compared with every single beam (lock-in amplifier dependent) CD.

After introducing the model 1000 in 1996, we added lower cost models with all the benefits of the proven 1000, less rapid- scanning detection.  In 1998, we introduced the model 16 as our double prism model, supporting a scan range of 165-700 nm. The model 17 was selected as our prism + grating model, supporting 185-1100 nm.  In 2000, these were joined by a small double grating monochromator with a spectral range of 170-700 nm: the Olis DSM 10.

Today’s data are an eclectic assortment of runs made on Olis CD spectrophotometers. Results above 185 nm are identical among the units. Results below 185 nm to approximately 167-170 nm are achievable by the models RSM 1000, Olis 16 and 10. Results including rapid-scanning (not shown in this collection of results) are possible only with the Olis RSM 1000 monochromator.
