Standalone Faraday Enclosure
Experiments in electrophysiology, confocal microscopy, and other sensitive applications often need to be shielded from external interference from electrostatic fields and electromagnetic waves generated by AM/FM radio, CRT oscilloscopes, fluorescent lights, and other common lab equipment. Thorlabs' Standalone Faraday Enclosure consists of a taut copper mesh that protects against these external sources of interference.

Magnets Hold Each Side Panel of the Enclosure in Place
Faraday cages minimize the influence of external electromagnetic waves on objects placed within them. Waves that are significantly longer than the mesh spacing will be blocked. Our Standalone Faraday Enclosure features a taut mesh made of Ø0.25 mm copper wire with 1.4 mm spacing. For easy access to the enclosure's interior, each of the four side panels are held in place by magnets and can be quickly removed, as shown in the photo to the right. The base plate of the Faraday enclosure includes an M3-tapped hole for attaching a user-supplied strap to ground the enclosure.
For simplified cable management, this enclosure comes with two port holes in the rear panel, each with a clearance of Ø1.75" (Ø44.4 mm). Additional port holes can be added using the PSY405 Cable Port Kit (sold below). To help further organize your workspace, our Faraday enclosure is compatible with our 25 mm construction rails via the PSY404 Rail System Adapter Kit (sold below).

PSY405 Cable Port Fitted to Faraday Enclosure
While our Faraday enclosure offers two cable ports on its rear panel, additional ports can be added to any Faraday enclosure panel using our PSY405 Cable Port Kit. Each cable port kit enables the creation of one additional port with a clearance of Ø1.75" (Ø44.4 mm).
To install a new port, place one plate on either side of the enclosure's copper mesh and bolt them together. Then use a sharp blade or scalpel to cut away the mesh from the center aperture. Finally, fit the included protective rubber ring to the hole. A manual with detailed instructions is included with each cable port kit.

Steps to Secure a 25 mm Rail System Inside a Faraday Enclosure
The PSY404 Adapter Plate Kit allows our range of 25 mm construction rails and construction rail accessories to be attached to the inside edge of the Faraday enclosure frame, as shown in the photo to the right. This allows custom enclosure and shelving systems to be constructed. A common application of this adapter is to construct a custom mounting structure within the Faraday enclosure that does not disturb the vibration-isolated experiment.
The adapter plate kit includes two adapter plates, two countersunk 1/4"-20 screws, and two countersunk M6 screws. Each kit allows the user to attach two 25 mm construction rails to the Faraday enclosure frame or to attach one 25 mm construction rail at both ends. The inclusion of imperial and metric screws permits both imperial and metric rail systems to be constructed.
For details on how to install the rails, please see the image to the right. In Figure 1, a countersunk 1/4"-20 screw from the kit is used to attach the adapter plate to one end of a 25 mm rail. Figure 2 shows two Low-Profile T-Nuts (our Drop-In T-Nuts can also be used) slipped into the frame. In Figure 3, the T-nuts allow the adapter plate to be attached to the rail using two user-supplied 1/4"-20, 3/8" long or M6, 10 mm long screws. One example of a possible final arrangement is shown in Figure 4.
