What is Radiometry?
Radiometry is simply the measurement of light. There are many characteristics of light that can be measured, but the most common are wavelength (color) related quantities and power related quantities, such as irradiance. StellarNet offers spectroradiometer systems for...What is Color Rendering Index (CRI)?
The color rendering index is a way to quantify whether colors under a light source will look the same as in daylight. This is reflected (figuratively and literally) in the light source’s spectrum. A light source with a spectrum that is different than the sun will have...What is the ChemWiz Concentration Predictor?
The ChemWiz Concentration Predictor makes use of the Beer-Lambert law (see absorption spectroscopy) to predict the concentration of unknown samples. It can be accessed by clicking “Applications” > “ChemWiz Methods,” “Chem,” or the chemistry glassware icon. By...What is light Intensity/Absolute Intensity/Irradiance?
What is Light Intensity, Absolute Intensity, and Irradiance? Light intensity is commonly used to describe the amount of optical power falling on a given area. In spectroscopy and radiometry, the more precise term for this quantity is irradiance. Irradiance is defined...Introducing our new Applied Spectroscopy Division
