This is the 25mm 720nm I bought have not personally measured the thread pitch, but it fits in very well in a C-shaped hole There must be a decent number of threads per inch on the mount flange.

Selected User Reviews For Green.L 49mm IR 680 Glass Infrared X-Ray Filter 680nm IR Filter for Camera Lens Digital DSLR SLR
When used with a PS3 Eye camera, this is excellent for tracking heads. For blocking light, I built an IR clip and used the usual film from a floppy disk. However, it does not function as well as it should. There is nothing bad to say about this filter it works well, fits well (with a little hot glue gun action), and is simply reliable. Without my glasses interfering, I am able to wear them. LEDs, etc. , are easily visible in the IR spectrum.
It's what we use on our NV nodes, it'll protect your 7-inch screen The tubes will be damaged if you are more than 15k from light sources. The 30mm screws in easily and is fun to use. Many people do not share these tips with you, but you can never go wrong with them.
I was surprised at how well it turned out.
A full spectrum camera that has been converted works very well with this plugin. Postprocessing the results of using a custom white balance results in great results.
I am very happy with it. My first roll of IR processing went smoothly and I am totally pleased with the results. Delivery is fairly quick and at a good price.
An invisible enemy can be seen by using this tool.
As for fitting the lens onto my camera, it was easy to do. The screw seems to be made of metal instead of plastic as I have seen with other lenses I have owned before. The overall experience I had with this product was satisfactory.
