Chapter 6 Pure Air
OSA instruments have two hose connectors which can be connected to an external air purifier, such as Thorlabs
Item # PACU Pure Air Circulator Unit. We recommend a flow rate of 2 liters/min. Simply attach two hoses (one
supply and one return) to the 1/4" inner diameter quick-connections on the back of the OSA. Compatible tubing
is sold as Thorlabs Item # PACU-TG.
WARNING
If purging gas other than dry air is used, make sure that the environment for the operator is well
ventilated since the gas will leak out from the instrument.
