Night Vision - Help me proof out my 1st NV set up.

[GTF425]

Bumping this thread again...

I am in the market for a focusing device for my PVS-14.

What other option are there out there besides Phokus Hoplite and Matbock Tarsier Eclipse.
I have zero experience with either one of the above and have made a home-made version that is not cutting it.
I like the looks of the Tarsier Eclipse but $250 seems a little high for an aperture.

The GWOT era answer is to take a Butler Creek flip cap and poke a 5.56 hole in the middle of it.

Here is what I used to make the one above.
Adjustable 1.5-26mm Iris Diaphragm M30 to M37 Camera Lens Module Adapter Ring https://a.co/d/0GWDKi9
And
K&F Concept 37mm MC UV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant Ultra-Slim UV Filter for 37mm Camera Lens (Nano-X Series) https://a.co/d/gLjiRZB

Just screw the lens into the iris and then the iris into the pvs-14. I like this better thN the original as I can just turn the outer ring and not have to look for the little adjustment lever that changes position based on its settings and how I have the focus set.

A HS guy had me do that.
It works just ok and if you need it in a pinch.

Initially I thought this home brew idea was gonna be a ram shackle type fix.
I had saw the recoomendation before and after your post. After a few bourbons, I said fk it and ordered the parts.
Turns out, it is a great solution. Screws right into the PVS-14 and works phenomenally better that putting a hole in a cap cover.
I think total cost was $70.

What is the purpose of this?

To make a focusing device that works well and is cheaper than a commercial version.

Whats wrong the factory focus? I haven't noticed a problem.

The iris doesn't really change focus per se, but depth of field. Changing the focus on your eye piece means you're locked in to the focal depth you've chosen; using an iris or cap means you've increased your DoF, so you can focus in closer without losing your infinity focus (or whatever focal point you had chosen).

I know some folks prefer holes in caps over an iris, due to the fact that the iris is infinitely adjustable, and you end up fiddle****ing with it too much, particularly with dual tubes, to get it right/matching, while the caps give you only a couple of presets. I haven't messed with an iris before, but I'm very fond of my Dark Focus Concepts caps, though the guy behind it is also a personal friend, so I'm biased in that regard.
