TUBE SPECS
Our Photonis Vyper Binocular :
PHOTONIS ECHO GEN 2 WHITE PHOSPHOR
- Superior resolution across light levels
- Superior auto-gating technology
TUBE SELECTION
For our in stock inventory, we list the center resolution (LP), SNR, EBI, Halo, and FOM.
Center resolution is much like resolution on a screen, the higher the better. However, for a head borne system, a resolution over 64 is indistinguishable to the naked eye.
SNR, or Signal to Noise Ratio, is essentially low light resolution. It is the single most important spec, in our opinion, for determining low light performance. The higher the better!
EBI, or Equivalent Background Illumination, is essentially the lowest light level that a tube can produce a usable image. Sounds important right? It is, but the importance is usually grossly overstated. The truth is, anything UNDER 2.5 will be just fine for 99% of users.
Halo is the ring or bloom around a light source when viewed through an image tube. The lower the halo value, the smaller the bloom.
FOM, or Figure of Merit, is obtained by multiplying center resolution by the SNR. We recommend ignoring this value when selecting a tube. Instead, examine its components separately as it doesn’t always accurately depict a tube’s performance.
