ATN PS31-3WN Binocular Night Vision Device + Green Phosphor
ATN PS31-3WN – a compact dual-tube Gen 3 binocular night vision device designed for observation and navigation in low-light conditions. Thanks to two independent optical channels, the device provides natural spatial perception and allows for more comfortable distance assessment to objects while moving.
The compact design and weight of approximately 580 g make the PS31-3WN suitable for helmet-mounted use. The housing is designed for operation in demanding conditions, while water and impact protection additionally enhances the practicality of the device during field use.
Features of the ATN PS31-3WN
The PS31-3WN uses a dual-tube design with independent adjustment of the optical channels. The device features 1× magnification, preserving natural perception of the surrounding environment without additional image magnification.
The optical system with an f/1.26 aperture and Proshield coating provides system operation in low-light conditions. Depending on the configuration, the field of view is 40° or 51°.
For operation at different distances, focusing from 0.25 m to infinity is provided, while diopter adjustment within − 6…+ 2 allows the device to be adjusted according to the user's vision.
The design also provides interpupillary distance adjustment from 54 to 88 mm, allowing the position of the optical channels to be adjusted to the individual user.
The device is equipped with automatic brightness adjustment and a bright-light protection system. The built-in IR illuminator can be used to improve operation in conditions of virtually complete absence of visible light.
