• Four 2-56 Threaded Holes in Front Plate to Secure FiberPort
• 8-32, 1/4"-20 (M6), and M4 Mounting Holes in Base

The L-Bracket FiberPort Post Mount has four 2-56 threaded holes for securing a FiberPort to the front plate, as seen in the photo to the right. The bottom of the L-bracket can be easily attached to an optical table, a breadboard, or a post since it has 8-32 and M4-threaded holes as well as a counterbored through hole for a 1/4"-20 or an M6 screw.

HCL Adapter Mounts FiberPort to HeNe Laser
Mounting Details

• Attaches to Lasers That Have Industry-Standard, 4-40 or M3 Four-Bolt Patterns
• Central Bore with C-Mount Threading
• Mounting Cap Screws with 4-40 and M3 Threading Included
• Four 2-56 Screws Included for Attaching a FiberPort

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.

FiberPort Mounted onto a Self-Contained
HeNe Laser Using an HCL2 Adapter

• External 5/8"-32 Threading is Compatible with Thorlabs' Self-Contained HeNe Lasers
• 5/8"-32 External Threading
• Slip Plate Design for Coarse FiberPort Alignment

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.

• Integrates FiberPort Products into 30 mm Cage Systems
• Allows Stable Fiber Launch Solutions for Cage System Applications
• Directly Compatible with Our Ø1" Lens Tubes
• Mounting Screws Included

The CP08FP(/M) is designed to center a FiberPort inside a 30 mm cage system. ER rods can be inserted into the four holes provided in the adapter as shown in the boxed image to the right. In addition, the four 2-56 stainless steel socket head screws necessary to secure a FiberPort to the adapter are included, each of which is 1/4" long. The cage plate has internal SM1 threading, enabling it to be used with our extensive line of lens tubes.

The CP08FP features enhanced cage-rod flexure clamps, which are designed to securely hold the cage plate in position for greater stability of the FiberPort system.
