Description

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. 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. 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. 1. When wiping the lens, use the supplied flannel or other soft and clean cloth, preferably with a professional lens cloth. 2. When removing residual dirt or smudges, one or two drops of alcohol may be dripped, and it may not be wiped with water. 3. Don't use the binoculars to directly observe the sun. The intense sunlight is focused by the binoculars. Just like the magnifying glass, it will burn your eyes. 4. do not fall, heavy pressure or other violent actions on the binoculars, which can easily lead to ghosting or lens damage. 5. In windy and humid weather, it is best not to use a binoculars, sand and water vapor will cause damage to the binoculars lens. 6. If the binoculars body is moldy, it shouldn't be dismantled and cleaned by itself. It is best to send it back to the original factory for repair. Don't attempt to clear the inside or disassemble the binoculars. It is best to have a professional on your side it when disassembling it. 7. When not in use for a long time, put it in a compact bag or electronic moisture-proof box with moisture-proof beads, but do not put it in the leather box, because the leather box is prone to mildew and water absorption.
