How Do I Judge Night Vision Quality?
For thermal it's easy. It's all about resolution, with 640 x 480 usually being the best for handhelds. A good system is 320 x 240, and there are many applications where 240 x 180 will do the job.
Judging the quality of I² equipment is considerably more complicated. The quality of any I² tool is determined by its optical characteristics as well as its image intensifier tube. You could take the best Gen 3 tube on the market and pair it with lousy optics, and you'd have a lousy system. So concern yourself as much with the optics as the tube
