Technical Note-Resolution

Posted on: August 25th, 2021

Among the many applications of spectroscopy, we encounter different types of resolution ranging from temporal, spatial, and spectral resolution. When evaluating a spectrometer instrument, the optical resolving power of the instrument is key. This is known as spectral resolution and is normally defined as the minimum spectral separation between peaks that the instrument can resolve.…

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.
