HeNe FiberPort and Threading Adapters
Thorlabs manufactures a line of FiberPort and threading adapters for both our standard (cylindrical) and Self-Contained HeNe Lasers. We also offer a Laser V-Mount for Ø1.5" Posts and a 60 mm Cage Mount for Cylindrical Lasers.

SM05AHN Adapter Connects SM05 Lens Tube to HeNe
The SM05AHN Adapter allows SM05-threaded components to be attached directly to the front of a standard cylindrical HeNe laser (mechanical drawing shown below). It contains four counterbored slots that fit industry-standard, 4-40 and M3 four-bolt patterns. This adapter is ideal for enclosing a HeNe beam path using SM05 Lens Tubes.
The HCL Adapter allows a FiberPort to be directly attached to the front of a standard cylindrical HeNe laser (mechanical drawing shown below). Equipped with a four-bolt pattern on 1" centers, the adapter comes with the necessary 4-40 and M3 cap screws for attaching it to the HeNe laser body, as well as the additional four cap screws needed to attach a FiberPort. The four-bolt pattern on the HCL accommodates both the M3-threaded Ø1.38" (Ø34.9 mm) and 4-40-threaded Ø1.47" (Ø36 mm) standards. For added mounting options, the HCL also has internal C-Mount (1.000"-32) threading, which is utilized on some lasers.
For cylindrical lasers, the 2.0 mm focal length PAF2-2A and 4.6 mm focal length PAF2-5A FiberPorts, which are compatible with the HCL, are recommended. For more information, please see the Selection Guide tab on our FiberPorts page.
The SM1A32 Adapter allows externally SM05-threaded or internally SM1-threaded optomechanics to be attached to the output aperture of the HNLS008R(-EC) or HNLS008L(-EC) Self-Contained HeNe Lasers.

FiberPort Mounted onto a Self-Contained
HeNe Laser Using an HCL2 Adapter
The HCL2 Adapter, which features external 5/8"-32 threading, allows a FiberPort coupler to be attached directly to the threaded aperture of our self-contained HeNe lasers or any other 5/8"-32 tapped hole. A slip-plate design allows the position of the FiberPort to be shifted and locked to maximize coupling efficiency. FiberPort mounting screws are included.
