ED glass effectively compensates for chromatic aberration (chromatic aberration = different coloured parts of a light beam are refracted to different degrees - can be clearly seen as a colour fringe along edges)

A good birdwatching telescope rewards you with excellent image brilliance and colour fidelity!

With a watertight lens, a clean and dry gas filling in the form of an argon or nitrogen filling creates an "internal climate" that prevents fogging.

The different types of DDoptics binoculars Binoculars can be divided into two main types according to their basic construction: Construction with roof prism (different types of construction) or with Porro prism. Both designs have their unique advantages and disadvantages. In principle, Porro and roof prism binoculars can offer the same performance depending on the type of glass (BAK 4, crown glass, etc.), the amount of coating required and the manufacturing quality. The details determine whether it [...]

For spectacle wearers, all DDoptics binoculars are equipped with retractable eyecups. This makes observation easier and enlarges the field of vision. 

The retina of our eyes has two different types of sensory cells or receptors, the cones (for day vision) and the rods (for night vision).

Additional protection of the binoculars in harsh conditions is achieved by applying a hard-wearing rubber armouring to the binoculars housing.

A state-of-the-art position and movement sensor registers every movement and the position of the optics. A controller interprets this data so that the illuminated dot is there when you need it.

Alignment in binoculars refers to the parallel alignment of the two halves of the binoculars.

Light transmission is the ability of optical glass or optical systems to "let through" as many light rays as possible.

For night glasses, which are ideal for sitting game and as sow glasses, the light intensity is the most important feature.

Pocket binoculars, often referred to as mini binoculars or pocket binoculars, are usually binoculars of the smallest design.
