Superior NIR Performance.

Olis DSM 17 CD UV/Vis[NIR] spectrometer Our model 17 is built around the classic Cary 17 UV/Vis/NIR monochromator. Of our three CD, this one feature the (1) widest available spectral range available span of 185 – 2600 nm (2) slit width under computer control and (3) full use of the renown Cary prism-grating monochromator for dual beam absorbance and circular dichroism.

Olis DSM 20 CD UV/Vis[NIR] spectrometer The model 20 is built around the Olis Hummingbird monochromator. Of all CDs in the world, this is the smallest. It is (1) designed for use in an amazing diversity in layouts (2) furnishes brilliant light throughput and (3) is completely approachable for students as well as senior staff. The Hummingbird is a subtractive double monochromator, also used in the Olis DB 620 absorbance and Olis DM 245 and 445 fl uorimeters.

Circular Dichroism ModelsExpectation - Exploding Rapid-Scanning

Olis DSM 1000 CD UV/Vis[NIR] rapid-scanning CD spectrometerThe model 1000 is built around a DeSa monochromator, the only rapid-scanning monochromator in the world. Like the model 20, the model 1000 supports maximum modularity and endlessly diverse applications. The F/4.5 monochromator (1) has the highest light throughput of the three choices (2) provides exciting potential for completely novel experiments and (3) is the fi rst choice for those comfortable with higher price tags on premium laboratory instruments. The DeSa “RSM” is a subtractive double grating monochromator capable of millisecond scan rates, also used in the full Olis RSM 1000 line for absorbance and fl uorescence.

This is the only rapid-scanning CD instrument available anywhere. Rapid-scanning is useful for FDCD, CPL, LD, and other secondary measurements for which an Olis DSM 1000 is confi gured. Rapid-scanning is possible throughout all spectral ranges, deep UV to far NIR. Best results presume meaningful signal strength and a modest spectral span.
