The device designed with all fiber structure. Fiber in and fiber out cell is applied to the spectrum analysis and detection of various gases. The optical structure of the gas cell is designed by independent patent design(Boss Gas Cell), with excellent optical stability, auxiliary and high stability optical packaging structure, mainly composed of gas cell cavity, reflector, standard optical fiber connector, gas import and out port, and shock proof base. The unique design of suspended light path, with excellent vibration and temperature stability, can work steadily in a variety of complex environments, and is very suitable for on-line real-time detection of various gases. It has low system noise and can be applied to trace gas analysis.

Safety and Operating Considerations
This device operates under reverse bias voltage, and the polarity of the device can’t be reversed.
Operating the Photodiode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power.
ESD PROTECTION—Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling Photodiodes.
