it has the same input as a 10160 but i have not had pvs5 lenses so i dont know how they would focus to this tube - the pvs5 i think uses a fibre optic input so the lens might not focus far enough back to get infinity focus as the 9855 will have to focus further back because of the glass input , if you have a 10160 tube to try the focus then it should work with the 9855

A f9855 tube is;
-Greater in diameter
-Has glass imput which is even thicker than that of a 10130 or 10160 tube.

So without a great amount of alterations it won't work.

Hi, my pvs 5 has a pvs-14 outlook lens(is it call pvs-5c, or pvs-5d, I confuse about it), is it possible to get focus?

About the housing, I will try to Polished from 43mm to 44mm (actually just try)

Thank you

It may appear that it is the same as a pvs14 lens. But optically they are different. It will not focus or only at very short range (15cm)
