TRIPOD CONNECTION
Many binoculars have a tripod thread built in. These binoculars can be screwed onto a tripod using an adap-
tor, which guarantees a static image.
COATING
Normal optical lenses refl ect part of the light falling on them.
This causes a loss of light and a reduction in contrast due to light scatter.
Coating the lenses by steaming a refl ection-reducing mineral layer onto them greatly reduces refl ection and
increases light transmission (permeability).

Coating the lenses by steaming a refl ection-reducing mineral layer onto them greatly reduces refl ection and

This is a coating of 7 to 15 layers of ruby-coloured mineral steamed onto the objective lens. It increases
image contrast in sunlight, as the red spectrum is mainly fi ltered out. However, the luminous intensity of
the instrument is reduced by approximately 7%. Fully coated binoculars let approximately 60% more light
through than uncoated ones. Special coatings (UV, multilayer) can be used to increase luminous intensity
even further.
