General information

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.

filled_with_nitrogen

High-end binoculars are completely airtight after being rinsed with dry and dust-free nitrogen. This guarantees a condensation-free and dust-free function. [Read more about a nitrogen filling](/en/ct/binoculars-glossary-nitrogen.htm).

Filled with nitrogen

prism_system

The prism ensures that the image is projected upright onto the eye. Read more about [roof prisms](/en/ct/binoculars-glossary-roof-prism.htm) and [porro prisms](/en/ct/binoculars-glossary-porro-prism.htm). 

Prism system

tripod_mountable

If the binoculars are tripod compatible, there is a cap in the front of the binoculars. You can remove this cap and place the binoculars on a tripod adapter. The whole is placed on a tripod. With a tripod you prevent your hand from shaking. As such you have a more stable image. 

Tripod mountable

value_close_focus

The close focus is the shortest distance at which you can focus your binoculars. An important specification if you want to study insects and butterflies.

Close focus

The front lens is the front lens of the objective. The diameter of the front lens is used to calculate the exit pupil, the twilight number and the brightness of the binoculars. [Read more about front lens diameter](/en/ct/binoculars-glossary-front-lens.htm).

value_exit_pupil_diam

The exit pupil is basically the circle of light produced by the binoculars that the eye has to catch. The exit pupil is calculated as follows: diameter / magnification. [Read more about exit pupil diameter](/en/ct/binoculars-glossary-exit-pupil.htm). 

Exit pupil diameter

value_eye_relief

Eye relief is the distance between the ocular lens and the exit pupil. Eye relief is particularly important for people who wear glasses because their eyes are situated further from the eye piece than people who do not wear glasses.

value_max_pupilary_dist

The interpupillary distance is the distance between the pupils of both eyes. The average distance for adults is around 65 mm. The interpupillary distance of the binoculars can be adjusted by moving both halves of the binoculars outwards or inwards accordingly. [Read more about interpupillary distance](migrated_topic_136).

value_twilight_factor

The higher the twilight factor the more details you will perceive. The twilight factor can be calculated by first multiplying the magnification by the objective lens diameter and then finding the square root of the result.
