The “DeSa Subtractive Double Grating Monochromator with Moving Intermediate Slit” is a unique technology and patented F/4.4 monochromator which we use in absorbance, fluorescence, CD, and LD spectrophotometers.
feature
exceedingly low stray light, high photometric accuracy, photometric precision, and other superb optical characteristics.millisecond scanning is not done by moving the gratings, as it done with traditional scanning instruments. Instead, to achieve 230,000 nm per second, the Olis RSM 1000 utilizes a moving intermediate slit wheel. This simple 'spinning intermediate slit disk' technology was awarded a US Patent and an R&D 100 award in 1994.
The RSM utilizes photomultiplier tubes (PMTs) for the UV/Visible range and InGaAs detectors in the NIR. PMTs are the most sensitive and fast detectors available and are usable over wide wavelength ranges and over wide dynamic ranges.
