L3H Unfilmed White Phosphor | Photonis Echo WP | Harris ITT GP | Comparison Gen 3 Night Vision

IMPORTANT The filmless WP tube’s specifications used in this video are: photocathode sensitivity 2763, 72 resolution, 34.2 signal to noise ratio, 0.8 EBI, 62,779 gain, and halo 0.7. Not all of the zone 3 blemish tubes will have these same higher specs. As of 5/26/20 it is my understanding that N-Vision changed their policy and no longer allows you to select or request tubes. It is best to contact them for more information. You can find the PVS-14 with zone 3 blem L3 filmless white phosphor here: https://nvisionoptics.com. They have a 10 year warranty. PVS-14 Photonis Echo Plus WP's and Harris HP+'s are at a bunch of places but check these for 10 year warranties and the best prices: www.jrhenterprises.com, www.tnvc.com, and www.nightgoggles.com This is not a sponsored or paid video. These are my personal items.
