In the early 1940s, the first commercial dispersive spectrometers emerged for UV-Vis applications. This technology is based on the dispersion of light in dependence of its wave-lengths. The dispersion ...

The optical spectrometer plays an indispensable role in many scientific and industrial applications, such as material analysis, biological sensing, optical tomography and hyperspectral imaging.

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

Spectral resolution is the most important feature of a spectrometer. This parameter determines the maximum number of spectral peaks that can be achieved using the system. For example, in the case of a ...
