Looking for data or photos related to the Fenn NG700D NVG, specifically the mount.

I take it you've looked here?

yes, and we've been in contact with Fenn, we were prepared to buy the actual mount from Fenn in support of a development project we are working on; but the lead time was longer than we could accept; we can reverse engineer it, but with limited data the NRE time and cost is impacting our project schedule. I'm looking for metrics, photos, or even a used/broken pair to purchase, again, I only need the mount, not the optics

MG - You and I were the first poster in this thread some sixteen years ago... How time flies

[MightyGem]

So we were. A lot of hours flown since then.

Does anybody out there wear contact lenses with NVG? Thinking of ditching my reading glasses which are generally perched on the end of my nose whilst on NVG.

Hi efish
My solution for reading glasses was to put them fully over my eyes and focus the tubes for them rather than the 'tip of my nose' solution which I tried first (couldn't focus in the ground cushion because I was looking down through the glasses).

With the glasses fully over my eyes, I could see through the goggles, up through the top of the glasses to see overhead switches and down through the bottom of the glasses to see instruments and radios. Only downside is when you de-goggle, you are looking through the reading glasses which isn't great for seeing the outside world.
Basically, goggles are for youngsters :-(

Cheers

Thanks Tees,


Just read the CAA rules on Contacts and it looks like a non starter as I would need a month off flying getting used to the contacts.
I think I shall have to put up with glasses until I retire in 4 yrs. And then I think I might splash out on some laser eye surgery.
When I googled contacts and NVGs, apparently some time in the future we'll be flying around with Night vision contact lenses with built in HUD! Wonder if they'll be daily disposables!!

Get some bi/varifocals. That way you look through the goggles using the top/distant half, and can view the instruments with reading part. Then there's no problem when you come off the goggs.

I flew on goggles for years like this.

[Letsby Avenue]

I never cracked NVG and reading glasses, used to wear the glasses round my neck on a cord like an old duffer... Best solution was to fly with the goggs in the door pocket and stick em on when I needed them. Required a degree of anticipation somewhat.

Hi MG
I think the ideal solution for me would be tri-focals with reading top and bottom and neutral in the middle. Sadly, I'm too much of a cheapskate and buy mine from ASDA for £2; I don't get upset when I lose them that way.

Tees.


If we work for the same organisation it looks they will now pay for eye tests and lenses, Result!
