Knight Optical’s Gas Cells for use in the Chemical Analysis

09 Sep 2021

We supply a range of Gas Cells for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications.

Knight Optical supply precision optical components to customers within the chemical analysis industry. Gas cells are used in spectroscopy for identification of the contents of gases. The path length and window material are chosen for analysis of different concentrations and types of gas.

Depending on the types of gases being analysed, the windows in a gas cell can be made from NaCl, KBr, CaF2, BaF2, or ZnSe and will be chosen depending on bandwidth, to meet the customer’s application.

Typical specs:

Material: NaCl, KBr, CaF2, BaF2, ZnSe or stainless steel bodies

Shape: Short Path, Long Path, Variable Path

Dimensional Tolerances: +/- 0.1mm

Parallelism: < 3 arcminutes

Surface Quality: <60-40 Scratch/Dig

Transmitted Wavefront Error: < 0.25 λ PV@ 633nm

All our Gas Cells are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Zygo Verifire Interferometer and Trioptics PrismMaster. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
