(9030DS) Double Subtractive 0.1 m Compact Monochromator

The 9030DS consists of two 100 mm scanning monochromators placed in series in subtractive mode. Bandpass is determined by the width of an intermediate slit, but the 9030DS has a net output dispersion of zero because the monochromators are optically coupled so that the dispersion of the second grating cancels that of the first. This leads to homogenized wavelengths at the output port - there is no spectrum, only a single undispersed slit image - which allows the unit to act as a tunable bandpass or notch filter.
Stray light of all sorts is drastically reduced in a double monochromator, and in the 9030DS it is further minimized by the use of concave holographic gratings. It is ideal for applications where stray light is a problem - where there may be a strong scattered background, such as in spectroradiometry, Raman or UV measurements of solar radiation.
This price includes a standard set of slits including a standard intermediate (inverted) slit, but does not include gratings. We also offer customized intermediate (inverted) slits; please speak with your authorized Sciencetech technical support staff member.
