Items Not Included: We purchased this instrument from a large company that had an unwavering policy of not selling computers for data security reasons. Unfortunately, this applied to computers running instruments, as well as the PC cards installed in them. This instrument is in need of a computer and the OLIS PC cards that interface to the instrument. The customer can arrange the system be completed/updated through OLIS, and we can crate and ship the item to OLIS directly. We can also answer any technical questions OLIS has about the system if they need to evaluate it remotely. Not having the computer and PC cards makes this instrument incomplete, and it has been priced accordingly. Because this system is incomplete and in need of additional components to operate, it is being sold as-is. We can take more specific photos and our technicians can run tests at the potential buyers instructions for remote evaluation. The buyer also has the option of inspecting the system at our facility.

Product Family Overview

Olis RSM 1000 Rapid-Scanning Monochrometer System

  • Stopped-Flow, Flash Photolysis, and Other Challenging Data Acquisition Projects
  • High Speed Kinetic Studies can be Followed with Millisecond Scans
  • Open-Architecture Design Allows Sensible and Effective Modularity
  • Excellent Sensitivity and Low Noise


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.
