How to Build a Spectrometer
How to build a spectrometer - theory
This article describes how to model a lens-grating-lens (LGL) spectrometer using paraxial elements, addressing the dBase/kb-article/?ka=KA-01950esign process from the required parameters to the performance evaluation with Advanced OpticStudio features such as Multiple Configurations, Merit Functions and ZPL macros.
How to build a spectrometer – implementation
This article describes how to implement a lens-grating-lens (LGL) spectrometer using commercially available optical elements. It features the setup of the spectrometer and addresses the improvement and optimization of its design.
How to build a spectrometer – tolerancing
This article describes how to perform a tolerancing analysis, in OpticStudio, of a lens-grating-lens (LGL) spectrometer built of commercially available optical elements and how to compensate for assembly and fabrication tolerances.
How to build a spectrometer – Stray Light Analysis
The article covers the conversion of a spectrometer setup from sequential to non-sequential mode, the design of a simple casing and the quantitative analysis of light scattered to the casing and light contaminating the spectrometer’s line camera.
