Category: PVS-14 Info Guide

Below is a quick look at how to pick out a PVS14 for new users. Sometimes the “research” people do on night vision literally can just lead them in circles. Worse yet they get advice from people who’s circumstances or uses may not be similar to yours.

“What do the numbers and pictures mean?”

Since every single night vision tube is different, there are natural variations in tube performance and cosmetics from one tube to another. One tube may have several black spots, another clean, one tube may have low Ebi, another higher Signal to noise ratio but slightly higher Ebi. Which to choose?

At this point I would remind you that we are never more than a phone call or email away.

FOM is a term you will hear a lot about. It stands for Figure of Merit. Basically the Signal to noise ratio specification is multiplied by the Resolution of the tube to get this number. For example a tube with a Signal to noise ratio of 30 and a Resolution of 72 would have a figure of merit of 2,160 and all other specification aside, would perform more than adequately for 99% of the lighting conditions most people will face. The higher the FOM level- in general- the more performance you can expect from the tube. This means greater light gathering capability which helps in extreme low light situations.
