Effect of Slit Orientation on Emission Intensity

Illustration showing how slit orientation changes the volume from which fluorescence is measured: (a) vertical slit orientation; (b) horizontal slit orientation. Suppose each slit’s dimensions are 0.1 mm × 3 mm. In (a) the dimensions of the sampling volume are … Continue reading

Wavelength Selection Using a Monochromator

An absorption filter has one significant limitation—because a filter has a fixed nominal wavelength, if you need to make measurements at two different wavelengths, then you need to use two different filters. A monochromator provides an alternative method for selecting a … Continue reading
