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...What is the Spectrometer’s Baseline Offset?
The baseline offset is the number of counts generated by the detector when there is no light. Several sources of noise are always present, so it is impossible to have no counts. The main components of baseline offset are electronic offset, dark current, and readout...Spectral Properties of Er3+/Tm3+ Co-Doped ZBLAN Glasses and Fibers
X Liao, X Jiang, Q Yang, L Wang, D Chen – Materials, 2017 Abstract A series of Er3+/Tm3+ co-doped fluoride (ZBLAN) glasses and fibers was prepared and their fluorescence spectra was measured under excitation at 793 nm and 980 nm. Correlation between the...
