The ELF-FB20 or commonly referred to as the "Jerry-FB 2.0" is the next iteration of the wildly successful Jerry-FB Thermal Fusion Binocular Night Vision Goggle. Unlike a COTI which projects the thermal image through the front of the goggle and may cause intensifier burn-in from the thermal display, the ELF-FB20 is a true thermal fusion device that overlays the thermal image on output side of the night vision image (also known as "eye-side" fusion).
Another main drawback of COTI-based systems is the thermal signal is projected into the image intensifiers' input side, the thermal image tends to get washed out in bright situations (eg: urban, suburban, or dynamic lighting). In a true fusion system like the ELF-FB20, the thermal is projected and overlaid after the image intensifier tubes' output screen, completely removing any risk of thermal wash-out.
Another major benefit of true fusion systems is the ability to display the fusion in a different colour (eg: red hot mode), further enhancing situational awareness and ability for the operator to distinguish between night vision and thermal images.

The ELF-FB20 CHS Edition comes with key modifications that factory units lack:
- Physically re-aligning the thermal module for alignment between thermal image and night vision on the right pod. Factory alignment causes the thermal image to be substantially shifted relative to the night vision image and cannot be corrected in software
- New lockable objective lens D-collars (Made in Canada) that allows for infinity stops to be implemented. Factory objective lenses are not lockable and therefore infinity focus cannot be set
- Complete device collimation and alignment of all 3 optical channels (left-side NV, right-side NV, and right-side thermal) for best experience
Improvements over Jerry-FB Classic

The ELF-FB20 is assembled with your choice of NNVT 1400+ FOM, 1600+ FOM, Photonis Echo 1800-2200 FOM, Photonis Echo+ 2200+ FOM, 2200+ FOM, or Photonis 4G 1800-2200+ FOM, or NNVT Gen3 2000+ FOM white phosphor image intensifier tubes. Each ELF-FB20 is cleaned, assembled, purged, and tested in-house in Canada with precision tools using our digital nitrogen purging rig, downdraft table, and clean room. Each device will also be tested and collimated using our in-house Hoffman night vision test set and a full test report will accompany each unit.
