Also, since i get asked that very often and also see Questions about that here on the Forum a lot, here is some Quick "Guide" to remove the Hot Mirror for IR/UV stuff or Full-Spectrum Use of the Chronos (2.1 shown here, should be the Same or very simmilar on the 1.4, but please double Check on yours if you want to remove it there, never did THAT on an 1.4...). Sorry for the Blurry images, wasnt in the Mood to set up an Tripod for this, so this is just shot by hand, hope they are still sharp enough to show what is going on.

So, first Remove the Small Screw from the Bottom Of the Camera, screw it out completely. Then Drop out the Small Brass Rod that sits behind the Screw. Make sure to Remove the Brass Rod bevore Removing the Mount, to make sure to not drop it on th Sensor (or Hot Mirror). When Screw and Brass Rod are Removed, Screw out the Mount. I just made a Small Dot with a small Black Marker Where the CS-Mount Writing and The Line sits, so its a Lot easier to align it again when you need to remove it and Put it back on a lot. You would propably still want to propperly adjust your backfocus after that, but for my use its mostly good enough, and Pretty fast. When The Mount is Removed, two Small Screws and An small holding Plate becomes Visible. Those Two Philipps head Screws need to be removed, but again, be very carefull to not drop anything on the ot mirror or Sensor. Then, when the Plate is removed, the Hot Mirror itself can be taken out. Make sure to prepare Some Soft Clean spot to put it and avoid touching the Surface, for example by holding it at the Corners. After that, just Put the Mount + Brass Rod + Screw back in there in reverse order (or leave them out, if you use alternative Mounting solutions), and you are Ready to shoot.
