Nikon Introduces the Binocular Telescope 20x120 IV/25x120
November 13, 2019
TOKYO - Nikon Vision Co., Ltd., (Nikon Vision), a subsidiary of Nikon Corporation (Nikon), is pleased to announce the release of Binocular Telescope 20x120 IV, 25x120 and dedicated pillar stand with adapter.
Both Binocular Telescope 20x and 25x models realise a brighter, high-resolution image with a large 120-mm objective diameter. The Binocular Telescope 20x120 IV employs a superior optical system that achieves a sharp image with various aberrations effectively compensated. The Binocular Telescope 25x120 enables high-power and dynamic observation with superior image flatness while realising a wide field of view (64.7° apparent field of view).
The binocular body is an airtight and waterproof structure which prevents rain and night dew entering. Also, it is filled with nitrogen gas to keep the binoculars fog-free inside. High corrosion-proofing and shake-resistance features maintain performance over an extended life.
Attaching to the optional Binocular Telescope Pillar Stand w/Adapter enables stabler, and easier observation. These are large binoculars that can be used in a wide range of applications from professional to leisure observation, such as fishing, sailing, astronomical observation and surveillance purposes.
