Light Source Characterization, Emission: To characterize light sources or collect emission from a source or sample, a single monochromator equipped with a detector (PMT) is required. ARC’s SpectraSense / SpectraHub package is ideal for collection and analysis of the source emission. A filter wheel is often added to eliminate unwanted second order radiation. For extended wavelength coverage, a monochromator featuring a multiple grating turret and dual exit ports is often utilized, allowing acquisition from UV through IR. |
 |
Transmittance, Reflectance, Absorbance: In most cases a single monochromator with a broad band light source and filter wheel can be used for these applications. An appropriate sample chamber with detector is needed to complete the system. A source compensation detector is recommended to improve the stability of the measurements. |
 |
Fluorescence, Luminescence: In these applications a monochromator with light source can be used to select the excitation wavelengths. A filter wheel is recommended for eliminating possible excitation from second order radiation. Analysis can be performed in a sample chamber or by using a fiber optic probe.A second monochromator with detector is used to characterize the sample emission. A second detection channel for source compensation or dual beam normalization |
