N-Vision Optics TWS13 overview

  • 1Description

Improve the stealth of your tactical activities or hunting using N-Vision' TWS13 336x256 Thermal Weapon Sight. This sight can be connected to your firearm via an optional Picatinny/Weaver mount and allows you to follow your targets or game and make shot placements at night or during the day and see through fog, smoke, dust, and foliage. At the core of this device is the 336x256 uncooled microbolometer detector, which captures thermal images with a 30/60 Hz refresh rate. After processing, the video data is delivered to an 800x600 color OLED display for viewing. The functionality of this device allow you to have white hot and black hot palettes and four digital color reticles with adjustable contrast and brightness.

To match the unforgiving conditions of the battlefields, the composite molded polymer housing is water-resistant and impact-resistant. It is outfitted with an easy-to-use and ergonomic control panel, knurled diopter ring, wide compressible eyecup, and flip-out objective lens cap.
