Lens mount for Raspberry camera

This is a lens mount for Raspberry camera that I have designed for experimenting with IR vision.
In my set-up I'm using a Raspberry camera without IR filter; this feature will allow to use IR pass filters and play with IR vision even in daylight.
I'm attaching a link below showing the initial stage of my experiments:

The support allows to use M52x0.75 camera lenses and has standard GoPro mount that allows to use standard GoPro accessories.

The actual IR pass lens in my set-up are the following:

720nm
760nm
850nm
950nm
