Irradiance Measurement with Avantes Solar Simulator

Posted on: July 26th, 2021

Background/Applications: Spectral irradiance is the irradiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The two forms have different dimensions: spectral irradiance of a frequency spectrum is measured in watts per square meter per hertz (W·m−2·Hz−1), while spectral irradiance of…

UV Radiometry Spectra

Posted on: April 21st, 2021

Radiometry deals with the measurement of all optical radiation inclusive of the visible portion of this radiant energy. Irradiance is a parameter of radiometry that describes the amount of radiant power upon a surface per unit area. These measurements can be done in the UV, VIS and NIR wavelength ranges. Irradiance measurements are useful in…

Frequency Resolved Optical Gating

Posted on: March 18th, 2021

In this application note, we will explore one of the most popular techniques for ultrafast laser characterization, which relies heavily on spectral measurement action: frequency-resolved optical gating (FROG). As well as the key requirements for spectrometers used in FROG systems. This aids mode-locked lasers in providing accurate and reliable laser characterization systems.

Chemometrics/Fruit Analysis

Posted on: February 11th, 2021

The application of visible (400 nm to 750 nm) and near-infrared red (750 nm to 2500 nm) region spectroscopy to assess fruit and vegetables is an efficient way to measure the properties of the fruit, as opposed to multi or hyperspectral imaging. Vis spectroscopy targets color assessment and pigment analysis, while NIR spectroscopy has been applied to…

Understanding Spectrometer Resolution Specifications

Posted on: January 11th, 2021

Resolution is one of the key specifications discussed in a spectrometer purchase decision. But resolution specifications can be overstated by manufacturers if the proper means of measuring resolution is not well understood by spectrometer buyers. For one thing, maximizing resolution might not be recommended for specific applications and can actually impede performance. The purpose of…
