Multiple traversal absorption cell of minimum volume: design
This study optimizes the design of three-mirror absorption cells, minimizing volume while maintaining optical performance. It focuses on reducing astigmatism and image curvature for enhanced optical systems.
Area of Science:
- Optical Engineering
- Spectroscopy
Background:
- Three-mirror absorption cells (White, Bernstein-Hertzberg) are crucial for spectroscopy.
- Previous analysis by Edwards identified astigmatism as the primary aberration.
Purpose of the Study:
- To optimize three-mirror absorption cell design for minimal volume.
- To align cell parameters with preceding objective optics.
Main Methods:
- Analysis of the White/Bernstein-Hertzberg three-mirror cell configuration.
- Utilizing Edwards' formula for astigmatic image length calculation.
- Relating cell design parameters to volume and optical objectives.
Main Results:
