How to Check If the FOM Value of Your Night Vision Goggles Is Real
When buyers choose night vision goggles, they often see numbers like FOM 1,600, FOM 1,800, FOM 2,000, or even higher.
But one question is very common:
Is this FOM value real?
This is an important question, especially for dealers, wholesalers, and product buyers. A higher FOM value usually means a higher price. If the FOM is not real, the buyer may pay for a high-grade tube but receive a lower-grade product.
The good news is that buyers can do some basic checks before and after receiving the device. You may not be able to test the exact FOM value at home, but you can find many warning signs by checking the report, the device, and the image quality.
Below is a simple step-by-step guide.
