optical gas cell

Optosun produce Inline Optical Gas cells with various options, including,
wavelengths- 1550 or 1650nM, various fiber lengths with bare fiber or loose tube.
Connectors can be fitted as follows: FC/UPC FC/APC SC/APC  SC/UPC LC/PC

We can also customise the number of holes, the hole sizes and positions.

Our Gas Cells are used in various applications including:
Tunable laser calibration, Optical calibration, Medical equipment, Sensing, chemical detection, and various wavelength and instrumentation uses.

This device is the 1550nM wavelength version, the In Line Optical Fiber Gas Cell (IFGC) 1650 nm is available here
