Multi-Coated Green Film
The green film is a common multilayer film, and the AR passband is
wider.The multi-layer film can well eliminate the enlarged color
deviation of the scene for many rays of light, and improve the
brightness of observation.
BAK-4 Roof Prism
Roof Prism keeps outgoing and incident light in a straight line.
Its lens barrel is straight, and the sense of distance, stereo
vision, and size are also closer to the naked eye.BAK-4 glass is
finer (higher density), it can eliminate internal light divergence,
and it is clearer than BK-7 glass imaging.Stunning HD clarity-
BaK-4 prisms and multi-coated optics offer clear sharp images with
improved light transmission
Double Glue Achromatic Lens
Different glasses have different light dispersion properties, so
two different glasses will be used on a lens and bonded with a
"photosensitive adhesive" dedicated to precision optical
components, so that all chromatic aberrations can be neutralized.
