Key specs include:
- Minimum FOM: 1400
- Minimum Resolution: 64
- Minimum SNR: 22
The Jerry-31 goggles deliver great performance while staying lightweight and compact. You can adjust the brightness to your liking, and they come with built-in protection against bright lights. The goggles also feature IPD stops and an IR Illuminator, and each lens powers on or off based on how you move them. They also have a built-in dovetail mount that's ready for a G24 mount.
Key Terms:
FOM (Figure of Merit) is a metric used to evaluate the quality of night vision devices. It's calculated by multiplying the resolution (how clear the image is) by the Signal-to-Noise Ratio (SNR). A higher FOM generally means better image quality and performance. A very high Figure of Merit (FOM) for night vision devices is typically around 2000 or higher. Devices with FOM values in this range offer exceptional image quality and performance,
SNR (Signal-to-Noise Ratio) measures the clarity of the night vision image. It's the ratio of the signal (actual visual information) to the noise (unwanted interference or "static"). A higher SNR means the image will be clearer, with less interference.
