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.
