Thermal Excellence



Revolutionary HD, clear, thermal image

Thermion 2 LRF XL50 offers the highest level of thermal imaging. The image generated with the new 1024×768- pixel thermal sensor features high definition and rich detail ideal for uncompromised trophy identification. The silhouettes, anatomy & behavioural peculiarities of the animal are clearly visible and easily distinguished.

Extreme image detail on high zoom

Variable 1.75-14x magnification (x8 digital zoom) provides improved focus and better overall object recognition at significant distances. The HD-sensor allows to maintain a high level of image detail across the whole magnification range. The zoom changes either gradually in 2x step or continuously for a customized FOV / magnification ratio for each specific situation.

Precise laser range finding

Understanding the target distance is an essential factor in making the right decisions. The compact laser rangefinder with a range of up to 800 metres is seamlessly integrated into a slim design riflescope, the receiver and emitter are within clearance limits of a single optical channel.

Integrated ballistic calculator for long-range shooting

Thermion 2 LRF ensures accurate shooting at any distance. The built-in laser rangefinder provides the hunter with an exact sense of distance to the target while the sophisticated internal ballistics algorithm calculates the suggested POA for accurate long-range shooting. Simply create a ballistic profile for your shooting equipment, upload it to the Thermion’s memory with the Stream Vision Ballistics App, and turn your Thermion 2 LRF XL50 into a highly accurate and efficient long-range aiming tool.

Wide field of view for easy scanning

Thermion 2 LRF XL50 offers a wide field of view for easy scanning and spotting. Even at high zoom levels, the large-format sensor allows for a well-balanced FOV / magnification ratio.

Premium HD-class germanium optics

For a clear and detailed image field of view, the Thermion’s 2 LRF XL50 germanium F50/1.0 objective lens truly expands the advantages of an HD thermal sensor. The use of aspherical lenses and diffractive optical elements maintains a high aperture ratio with the capability of sharp and precise image projection across the entire sensor area.

High-precision ambidextrous lens focusing

Objective lens with internal focusing mechanism gives a clear and sharp image at any range. Ergonomic focusing wheels are located on the right and left sides, making focusing easy either left- or right-handed.

Ground-breaking image processing

The pixel-to-pixel image transfer from the sensor to the display makes the image as sharp as possible. Adjustable sensor sensitivity amplification combined with new filtration algorithms offers the hunter great opportunities for observation in diverse weather and temperature conditions. The amplification setting helps to define the animal’s trophy features and ensures clear rendering of objects and background in the field of view.

Wireless remote control included

The Pulsar BT wireless Bluetooth remote control completely duplicates the regular buttons. The remote control features excellent ergonomics − the buttons activate the most used functions, while rotating or pressing the encoder operates fine adjustment and menu navigation. The design, size and positioning of the buttons and encoder are customized for use with both bare hands and gloved hands. It takes minimum movement for a hunter to control the riflescope enabling them to maintain maximum concentration on the hunting process with the remote control placed in any convenient position on the fore-end or rifle butt.

Mounting on standard 30 mm rings

Mounting on standard 30 mm rings

The Thermion 2 LRF XL50 offers visual aesthetics on any hunting weapon. From the outside the riflescope resembles a classic day sight in a 30mm aluminum alloy housing. This form factor provides flexibility for mounting the scope on hunting weapons using proven ring solutions.

.375H&H ready

.375H&H ready

Thermion 2 LRF XL50 thermal riflescope is high impact resistant and can be used with rifled hunting weapons with calibers of 9.3×64, .30-06, .300, .375H&H, etc., as well as with smooth-bore and pneumatic weapons.

10 shooting profiles / 100 zeroing distances

10 shooting profiles / 100 zeroing distances

Zeroing settings are saved in a shooting profile. The Thermion 2 LRF XL50 memory contains up to 10 shooting profiles for several types of weapons or cartridges. Each profile holds up to 10 zeroing distances input manually, but can be transformed for automatic ballistic calculations based on measured distance using the Stream Vision ballistics app.

A selection of 10 reticle shapes in 9 color modes

A selection of 10 reticle shapes in 9 color modes

A reticle is electronically displayed in the same plane as the target. The Thermion 2 LRF XL50 memory contains ten reticle configurations and functions (direct shot type, ballistic, scalable and regular), all available in nine colors.

High-precision aiming in the «Picture-in-picture» mode

High-precision aiming in the «Picture-in-picture» mode

The “Picture-in-picture” function enables the shooter to display a high-precision zeroing frame. Taking only 10% of the total display area, the frame shows a magnified image of the target and reticle and allows the user to closely see the image in the aiming area and have visual control of the entire field of view at the same time.

Customizable user mode for individual image adjustment

Customizable user mode for individual image adjustment

Use the brightness and contrast adjustments to maximise the detail and informative value of the image in specific observation conditions. The User Mode function saves selected brightness and contrast settings in the device’s memory providing optimal image quality for the next use of the thermal imager immediately, with no additional adjustments needed.

Combined dual battery system

Combined dual battery system

The Thermion 2 LRF XL50  is powered with two rechargeable batteries: one built-in with a capacity of 4.9 A·h, and the other replaceable. The standard package supply includes replaceable batteries of 2A·h and 3.2 A·h capacity. A single charge guarantees up to 10 hours of continuous operating time. The embossing on the body of the replaceable batteries enables accurate determination of the correct position and enables replacing a flat battery with a new one quickly and confidently in complete darkness by touch alone.

64 GB memory photo and video recording

64 GB memory photo and video recording

Keep the best moments of observation and share them with your friends and hunting colleagues. One touch of a button is enough to capture an interesting moment or start recording a video. 64 GB of internal memory gives the ability to record many hours of video and tens of thousands of photos.

Flexible set of colour palettes for various needs

Flexible set of colour palettes for various needs

1024×768 HD AMOLED display has enhanced color rendering, power saving, a high contrast image and quick-response, providing clear and smooth images for on-the-move observation or in cold conditions. A choice of 8 colour palettes lets the users observe their field of view more effectively, allowing them to optimise the unit for specific tasks as well as react to changing observation conditions. White Hot, Black Hot and Red Hot are optimal for object detection, Rainbow and Ultramarine help increase chances for recognition & identification. Red Monochrome, Sepia and Violet are most suitable for long observation in the night.

Wi-Fi integration with iOS and Android devices

Wi-Fi integration with iOS and Android devices

The built-in Wi-Fi module with a dual 2.4 / 5 GHz waveband support connects the riflescope with smartphones based on Android and iOS via the Stream Vision 2 mobile application. This combination provides a great opportunity, such as wireless update of the device software, transmission of images to the screen of a mobile device in real time, remote control of digital functions of the device and many others. Users registered in the application are provided with cloud storage space for photos and videos taken with a  thermal imaging device.
