Features
- Cage Plate with Integrated Purge Port for Connecting Two SM1 Lens Tubes
- Compatible with Thorlabs' PACU2 Pure Air Circulator Unit and 30 mm Cage Systems
- Cage Plate Thickness: 0.75" (19 mm)
- Max Pressure: 30 psi (200 kPa)
- Two 8-32 (M4) Mounting Holes at 90° Positions for Ø1/2" Post Mounting
The CPPC Purge Connector for SM1 Lens Tubes makes enclosed SM1 lens tube systems compatible with our PACU2 Pure Air Filtration System via the hose barb. The barb is compatible with 0.18" internal diameter tubing, such as that included with the PACU2 system or the tubing sold below. The purge connector has SM1 (1.035"-40) internal thread to use with SM1 Lens Tubes or accessories. It also features four Ø6 mm bores for compatibility with our 30 mm cage system and is 0.75" (19 mm) thick. Each cage locking set screw has a 5/64" (2 mm) hex. The bottom and side of the cage plate also offer 8-32 (M4) mounting holes for post mounting.
We recommend using two or more CPPC Purge Connectors with our pure air filtration system, which has two connections: one for supply and one for return. The device incorporates desiccant and particulate filters in series and excels at providing an extremely clean, dry atmosphere for closed-loop experimental setups.
Note: The CPPC Purge Connector is strictly intended for purging or purifying the air in a lens-tube-enclosed beam path. Our lens tubes are not air tight and the SM1 thread is not suitable for pressurized or vacuum applications. Please do not apply sealant or tape to the thread.

(posted 2024-08-29 20:06:36.47) I am considering an optical path purge system. We intend to send dry air supplied from an air dryer to the optical path through the CPPC. I have a question about the air piping. When supplying dry air to the optical path, is it desirable to use piping that is branched from the main stream to fill the optical path? jdelia
(posted 2024-09-27 09:25:07.0) Thank you for contacting Thorlabs. As this is an application-specific question and not directly concerning the use of our part CPPC, we unfortunately would not be able to provide comment on this inquiry. I have reached out to you individually via email to check whether you need anything clarified regarding the CPPC or had any specific questions on its functionality. |
Zoom- Low-Outgassing Tubing for CPPC Lens Tube Purge Connector (Sold Above)
- 0.18" ID x 1/4" OD (4.6 mm ID x 6.4 mm OD), 1 MPa @ 20 °C Tubing
- Continuous Operation Temperature: -4 °F to 392 °F (-20 °C to 200 °C)
- Available in 13.1' (4 m) and 26.2' (8 m) Lengths
This clear low out-gassing tubing can be used with our CPPC Purge Connector to supply air or inert gas (N2) to an enclosed SM1 Lens Tube system. The 13.1' PACU2T4 tubing is included in our PACU2 Pure Air Circulator Unit. This tubing can be used in any application where maintaining high purity is critical, and is resistant to abrasions and many commonly used chemicals. It has a max pressure rating of 1 MPa at 20 °C and is available in both 13.1' (Item # PACU2T4) and 26.2' (Item # PACU2T8) lengths.
