Glass and Prism Quality
Bak-4 Prisms (barium crown glass) are the highest quality, producing no internal light loss.
Coatings help improve light transmission, especially in roof prism designs. This binocular is rated as FULLY MULTI-COATED, meaning that all surfaces have more than one coating.
The 15.3mm eye relief on this binocular provides superb viewing comfort for both spectacle and non-spectacle wearers.
This binocular has an exit pupil of 2.8mm, suitable for use in bright and light overcast daylight conditions.
