Night Vision Depot is one of the largest stocking distributors and manufacturers of night vision systems, image intensifiers and parts.  They are also now working with Knight’s Armament for some of their products, namely their PVS-22, BNS-LR-30, UNS-A2 and the UNS-SR.  It seems like the most effective use of the UNS models are to seat them in front of your existing optic.

Finally, they are offering a number of their Gen III devices in “White Phosphor”, which I have to say, is a lot cleaner looking than the traditional green.  There seems to be a little more contrast and I just plain like the color better.  This can be an upgrade to an existing system or you can buy them stock.  They have a number of models as scopes, monocles, or binocs. I have some pics from their media kit coming and will update with some sample images (until then you can see examples on their site).

They look just like the regular models–the important change is the tube inside.

All NVD products come with a 10 year warranty.
