Grating based Monochromator for Spectroscopy

Spectroscopy – the study of the spectral (wavelength) composition of light – remains an important field of study in optics. Poly- or monochromators, which employ the dispersive behavior of diffractive elements to separate the different spectral components of incoming light in different directions, are often selected for this task because of their ease of use and adjustability.

The “connecting field solvers” approach implemented in the fast physical optics modeling and design software VirtualLab Fusion can simulate complex systems made up of a variety of components, as is the case in this field: gratings and refractive elements (such as parabolic mirrors) are both unavoidable parts of spectroscopic systems. This capacity of VirtualLab Fusion to simulate realistic, complex systems with its fully vectorial, fast physical optics engine offers the optical engineer invaluable tools for the task of designing and analyzing this kind of setups. As an example, this week we present a classical Czerny-Turner monochromator and give a detailed insight into the properties of our grating component.

Czerny-Turner Setup

The Czerny-Turner setup – a famous historical example of a monochromator – is demonstrated in this use case, including an application of the setup to visualize the D-Lines of the sodium doublet.

Grating Component for General Optical Systems

This use case introduces the Grating component in general optical setups, which allows for the inclusion of a wide range of different gratings in complex optical systems.
