Over 30 years of experience in gas cell sales! A global supplier of gas cell technology!
Wavelength References manufactures gas cells as near-infrared and mid-infrared frequency standards for applications such as calibration, measurement, and gas sensing. Components from Wavelength References are installed in thousands of products worldwide. Reference gas cells rely on the principles of molecular absorption, particularly the vibrational and rotational modes of molecular gases such as acetylene, hydrogen cyanide, carbon monoxide, and hydrogen fluoride. Molecular absorption frequency standards have a clear advantage in being relatively insensitive to environmental changes and temporal variations, allowing for traceability due to the fundamental physics of molecular absorption. 【Features】 ■ Ideal for inspections in the near-infrared ■ Standard configuration: Acetylene, hydrogen cyanide, carbon monoxide, water vapor, hydrogen fluoride ■ Housing path lengths: 3cm, 5.5cm, 16.5cm, 48cm, 80cm ■ Fiber connector: FC or SC, PC or APC *For more details, please refer to the PDF document or feel free to contact us.

basic information
The fiber coupling reference gas cell is available in various configurations suitable for near-infrared inspection. The standard configurations include acetylene, hydrogen cyanide, carbon monoxide, water vapor, and hydrogen fluoride, but several other gases and mixtures are also available. The housing accommodates path lengths of 3 cm, 5.5 cm, 16.5 cm, 48 cm, and 80 cm (the latter two utilize a folded optical system within a multipath housing). The fiber connectors are FC or SC, and either PC or APC. An integrated photodetector output is also available as an option. These cells are used for calibrating spectrum analyzers, calibrating wavelength-tunable lasers, inspecting fiber Bragg gratings, and gas detection, among other applications. 【Standard Product Lineup】 ■ Acetylene (12C2H2) ■ Hydrogen Cyanide (H13C14N) ■ Carbon Monoxide (13C16O) ■ Hydrogen Fluoride (HF) ■ Methane (CH4) ■ Carbon Dioxide (CO2) ■ Water (H2O) *For more details, please refer to the PDF document or feel free to contact us.
