What is the Integrated Peak Area?
The integrated Peak Area, also called the power spectral density (PSD), is exactly what it sounds like: it is the integrated area under a peak in a spectrum. This gives a scalar value with a meaning that depends on the units of the spectrum. For example, in...What is the Peak Tool?
The peak tool is an application in SpectraWiz for calculating various peak related quantities. It can be accessed by clicking the green peak icon. The quantities it calculates are as follows: Peak: peak wavelength Centroid: centroid wavelength FWHM: full width at half...What is a Cosine Receptor?
A cosine receptor (sometimes called a cosine corrector) is a type of light receptor that is used for radiometry and photometry. It collects all light in a 180 degree field of view, making it suitable for measuring light from a planar surface or light from multiple...What is Photosynthetically Active Radiation (PAR)?
Photosynthetically active radiation is any radiation that can be used for photosynthesis. This is generally wavelengths in the visible range (400-700nm). Radiation outside this range is given zero weight. This is slightly different than photometry, which has...What is Photosynthetic Photon Flux Density?
The photosynthetic photon flux density is the amount of photosynthetically active photons (400-700nm) hitting a surface per unit area per unit time. The units are µmol (of photons) m-2 s-1.
