Thorlabs' Cage System Covers are designed to enclose 16 mm, 30 mm, or 60 mm cage systems. They can protect users from stray beams or wavelengths that are invisible to the naked eye, as well as prevent ambient light, dust, and other contaminants from accessing the beam path. Made from high impact polystyrene plastic, the cage covers are sold in 24" lengths, which can be easily cut to the desired length by the user; see the Cutting Tutorial tab for details.

Each cover features a tab on one side that provides an additional light seal and an area to grip during installation and removal. The covers snap onto the cage rods, as shown in the images to the right. To remove, simply pull the tab to release the cover.

Please note that these cage system covers are not light tight and should not be used in high-power applications.

I can just agree with Yongjin. Cutting as indicated in the tutorial is not working at all. The edges are completely askew and thus do not cover the end areas where the adapter/optic plates are. Without a mitre box saw this product is absolutely not working.

Thank you for the feedback. We're sorry to hear about the difficulty in getting this product to work as advertised. We will consider revising the web documentation to better reflect this.

The cutting is painful. The suggested method (cut the leg and snap) does not make a sharp edge (hope you try it yourself). I tried a hot knife, which worked better but is not perfect. It is also very tricky to use. Can you please provide any other suggested cutting method?

Thank you for your feedback. For a sharper edge, you can consider using a mitre box saw, which can be acquired at hardware stores for relatively cheap. I have reached out to you directly to discuss cutting options as well.
