SUMMARY
The Herriott-type Long-path Optical Gas Cell is targeted for use in applications like gas sensing, spectroscopy, etc., in which a long optical path is required. OELPC-100 comes with or without built-in isolated gas chamber. For efficient optical coupling, the cell can be attached with optical fiber pigtails. A beam entering the cell undergoes multiple reflections between two metal-coated highly reflective mirrors and the total length can be up to 100 m.
