Helion 2 XQ50F Features:

  • Highly Sensitive Thermal Imaging Sensor
    • Thermal imaging sensor with NETD 40mK ensures perfect detail recognition even in the hardest weather conditions when thermal contrast is low. The smallest temperature differences will be clearly visible during the rainfall, fog or cold mornings in the most difficult conditions for thermal imager.
  • Image Boost Technology
    • Pulsar’s proprietary Image Boost Technology is comprised of software algorithms designed to increase imaging clarity and overall image detail. Image Boost results in a sharper, more detailed field of view and enhanced object identification capabilities.
  • Ultra-high-strength magnesium alloy housing
    • The lightweight magnesium alloy housing stands out due to a high structural strength and resistance to external mechanical and climatic loads. The housing material effectively removes and dissipates the heat generated by the electronics, ensuring the operational stability of the thermal imager and maintains a high quality image during prolonged observation.
  • Variable Digital Zoom
    • Digital zoom, up to 8x depending on model, provides improved focus and better overall object recognition at significant distances.
  • Wi-Fi. Integration with IOS and Android devices
    • Built in Wi-Fi module provides connectivity of thermal imager with Android or iOS smartphones or tablets. The smartphone and thermal imager combination offers a set of unique features such as direct image streaming, downloading and sharing recorded files, firmware update and many other.
  • Long detection range
    • Powerful objective lens in combination with professional grade thermal imaging sensor with NETD 40 mK provides exceptional detection capabilities. A standard 1,8m tall object can be detected at a 1800 m (Helion XQ50F) / 1350 m (Helion XQ38F) distance in complete darkness.
  • Built-in photo and video recorder
    • The Built-in video recorder is a great asset when it comes to filming or taking photos of once-in-a-lifetime experiences. One press of the REC button captures footage that can be shared easily with colleagues, friends and family. 16 Gb of internal memory provide many hours of recorded video and tons of photos.
  • Large aperture lens
    • The characteristics of thermal imaging optics have a decisive influence on a thermal imagers ability to capture even the lowest radiation levels. Ultimate detection efficiency is achieved with the fast lenses of the Helion 2 XQ38F (F35/1.0) and Helion 2 XQ50F (F50/1.0) thermal imagers in combination with highly sensitive thermal sensors. The Helion 2 XQ models give users the best quality, most detailed & high-contrast, informative imagery every time, even during rain or fog, when the temperature contrast of the observed scene is minimal.
  • Full colour HD AMOLED display
    • The new 1024x768 HD AMOLED display has improved colour rendering, is power saving, offers high contrast imagery and a quick-response, as well as providing clear & smooth images when observing on-the-move or in cold conditions.

Additional Features:

  • Power Supply System B-Pack
    • Helion includes a progressive autonomous B-Pack power supply consisting of a quick-detach, rechargeable IPS7, 6.4 A-h battery pack designed to deliver over 10 hrs. of operation on maximum mode. Higher-powered IPS14 battery packs, as well as AA battery cases, also are available and provide a perfect off-the-grid power solution.
  • Stadiametric Rangefinder
    • Helion has a stadiametric rangefinder performed in the shape of rangefinding reticle which enables distance measuring to observed objects with known height (deer - 1,7 m; boar – 0,7 m; hare – 0,3 m) with a sufficient precision.
  • High image frequency
    • Due to the high image frequency (50 Hz) it is comfortable to use thermal camera dynamically (during rapid moving of observer or object of observation).
  • Updatable Software
    • For initial setup and additional updates, the iOS and Android compatible Stream Vision App ensures the most recent Helion software versions are available.
  • Wide range of operation temperatures
    • Helion thermal imaging scopes are effective for the use in low temperatures (-25°C) thanks to the frost-resistant AMOLED display employed in the unit (image remains the same as when viewing at positive temperature of the surrounding atmosphere).
  • User-friendly interface
    • The Helion is designed with ease-of-operation in mind. User feedback has resulted in the most friendly interface to date, complete with an easy-to-read, icon-driven, alpha-numeric status bar at the bottom of the display. Internal menu items and options are also displayed on a contrasting gradient substrate so you can keep an eye on settings without losing sight of your objective.
  • External Power Supply
    • Helion makes charging from external sources, such as power banks, fast and easy with a micro-USB jack. The convenience of power-bank charging even enhances the ability to power up the Helion during extremely cold weather while also protecting the source from rapid discharge.
