Olis RSM 1000 Rapid-Scanning Monochromator System

Since 1994, Olis RSM 1000 spectrophotometers have been selected by top research laboratories involved in stopped-flow, flash photolysis, and other challenging data acquisition projects. With the Olis RSM 1000, high speed kinetic studies can be followed with millisecond scans, not just fixed wavelength traces. Rate constants calculated from 3D data are more precise than those calculated from 2D data, and chemical models can be confirmed or rejected by examination of the same kinetic spectral data set.

Today, many Olis RSM 1000 spectrophotometers are configured for steady-state absorbance, fluorescence, and circular dichroism spectroscopy. Here, all of the high speed electronics are used with extensive over-sampling, resulting in excellent sensitivity and low noise. The open-architecture design allows sensible and effective modularity, so that one RSM can be used for rapid-scanning absorbance stopped-flow in the morning and steady-state circular polarized luminescence with only minutes of hardware rearrangement in between.

Whatever the measurement, be confident that you are using the premier optical bench available for microsecond and slower data acquisition modes, optimized for 1,000 scans per second and ideal for so much more.

A Breakthrough Monochrometer is the Center of all Olis RSM 1000 Spectrophotometers. The patented DeSa2 monochrometer spends all day long scanning 1,000 times per second over a spectral range in the UV, Visible, or NIR region with milli-absorbance sensitivity and absolute reproducibility. All optics are fixed in position. Scanning is effected by moving a (narrow) slit across an (25 mm) aperture at the intermediate plane of the double grating monochromator. This mode of scanning is possible only with a “subtractive” double grating monochrometer. In addition to millisecond spectral scanning, the DeSa “Subtractive Double Grating Monochrometer with Moving Intermediate Slit” produces a homogeneous output beam, very low stray light, very high photometric precision and accuracy, and a dark reading between every scan.
