Take you to understand the structure and principle of telescopes

Standard

Standard binoculars have a wide range of uses, which can be used for viewing or watching sports events.

   

Lightweight

Lightweight binoculars are characterized by being small and easy to carry. They can be used for concerts, mountain hiking or hunting.

   

Large diameter type

Large-aperture binoculars are the best choice for tracking fast-moving objects, such as football matches, track and field matches, wilderness terrain detection, etc.

   

Zoom type

The zoom-type binoculars can instantly magnify the magnification to see the details of the scene, and can also reduce the magnification to observe the whole scene. The near and far view is unobstructed and unobstructed.

   

waterproof type

The waterproof binoculars are filled with nitrogen and are sealed in a ring shape. They are waterproof and anti-fog. Even in foggy and humid weather, they will not affect the sharpness of the image. Of course, the price will be higher.

   

Coating type

The lens surface coating can reduce the loss of light caused by reflection, thereby increasing the brightness, clarity and contrast of the image, and can also reduce eye fatigue.

   

Coating

A single-layer antireflection coating is plated on at least one optical surface.

   

Full surface coating

All lenses and prisms are coated with a single layer film.

   

Multi-layer coating

At least one optical surface is coated with a multilayer antireflection film.

   

Multi-layer all-optical surface coating

All lenses and prisms are coated with multi-layer antireflection coatings.
