Powerful day & night optics
The Thermion Duo series features two multispectral riflescopes — the Thermion Duo DXP50 and Thermion Duo DXP55. Each riflescope combines the detection capabilities of thermal imaging with the identification capabilities of full-colour day optics in one intuitive device — enhancing your hunting experience and providing better situational awareness when observing targets at long-range.
- The Thermion Duo DXP50’s 12.4° FOV remains the same regardless of which optical channel the rifle is set to.
- The Thermion Duo DXP55 features a 12.4° FOV in the thermal channel and a 6.1° FOV in the digital channel.
Ambidextrous focusing knobs found to either side of the day optics housing have been added to ensure quick and easy focusing whilst remaining comfortable to operate. Fin levers can be found on these focusing knobs, allowing for quick and easy micro adjustments.

Classic design with traditional daytime riflescope aesthetics
Based on solutions and components found within Pulsar’s flagship Thermion 2 XP50 Pro thermal imaging riflescope, the Thermion Duo DXP50 features a seamlessly integrated day optics housing located on top of the riflescope that contains a full-colour 4K optical channel for high definition daytime observation.
This housing remains low-profile, allowing this new multispectral riflescope to retain the familiar aesthetics of a classic daytime riflescope, mounting using standard 30mm scope rings and ensuring it never looks out of place on a rifle.

European made thermal
imaging & 4K CMOS
sensors
Featuring a highly sensitive, European-made thermal sensor, the Thermion Duo series will offer an impressive thermal detection range of up to 1800m.
Its 4K CMOS sensor provides crystal clear daytime observation capabilities, with a full-colour HD image and accurate daytime colour rendering.
Advanced image processing algorithms and Pulsar’s smoothing filter will ensure this picture always remains as clear as possible and reduces eye strain and fatigue over long periods of observation.
Improved situational awareness with 640×480, 17µm, <18mK sNETD thermal sensor
Both multispectral riflescopes are fitted with a sensitive 640×480, 17µm thermal sensor capable of detecting even the smallest heat signature at distances reaching up to 1800m in varying weather conditions. Its outstanding <18mK sNETD thermal sensitivity makes it especially effective in adverse conditions where other thermal imagers would struggle, including dense fog and heavy rain.
These thermal sensors will provide enhanced situational awareness, effortless detection, and reliable identification; with an observed animal’s important anatomical details and the surrounding landscape presented in exceptional detail.
Powerful 4K CMOS sensor for enhanced daytime identification
Powerful 4K 3840×2160 CMOS sensors in the digital channel will present crystal-clear images at distances of 10m or more, achieving enhanced identification capabilities, with a full-colour HD image and accurate daytime colour rendering reminiscent of a traditional daytime riflescope.

More observation opportunities with combined viewing mode
These intuitive multispectral riflescopes provide you with multiple observation modes, including the ability to view both channels at the same time with combined viewing mode.
- Use the digital channel for daytime hunting with high-resolution images with accurate colour rendering and impressive identification capabilities.
- Use the thermal channel for enhanced detection capabilities during both day- and night-time hunting.
- Use combined viewing mode, which utilises the built-in Picture-in-Picture (PiP) functionality to present a secondary viewing box on the top 10% of the screen. Combined viewing mode allows for both digital and thermal channels to be viewed simultaneously, providing more information and enabling better situational awareness. You can even alternate between which channel fills the main viewfinder and which channel fills the small viewing box.
One-shot freeze zeroing in both thermal and digital channels
The Thermion Duo multispectral riflescope features one-shot freeze zeroing, freezing the zeroing screen and allowing users to make adjustments without having to hold the riflescope precisely at the initial aiming point. This means one cartridge is all you need to zero in both channels at your selected distance.
Once you have taken the ranging shot, the riflescope will take a photo of the target, at which point the thermal and digital channels will be set at the bullet’s point of impact.


Exceptional image detail through Pulsar’s advanced image processing algorithms
Both riflescopes in the Thermion Duo series use Pulsar’s set of advanced image processing algorithms, providing a truly outstanding visual experience with enhanced image detailing, clarity, and contrast.
With its wide range of halftones, the Thermion Duo’s thermal channel is more than capable of rendering complex scenes with evenly emitting low-contrast objects (i.e. the sky, grass, or bodies of water), ensuring greater levels of informativity in the field.
Improvements can be made to the quality of the riflescope’s detection capabilities when environmental conditions start to deteriorate through manual adjustments of the thermal sensor’s sensitivity level.
Pulsar’s smoothing filter, along with brightness and contrast controls, enable more comfortable long-term observation.
Automatically transitions
from day to low-light
mode
When the sunlight begins to subside and light levels change, the Thermion Duo’s daylight sensor will automatically switch from colour mode to black and white mode. This ensures the digital image’s low noise level, clarity, and high definition is maintained through the evening, all the way to sunset.


Built-in ballistic calculations with Stream Vision Ballistics compatibility
The release of Pulsar’s firmware update 3.3 for Thermion Duo and Digex C50 models introduced ballistic calculations to non-LRF equipped riflescopes, with Stream Vision Ballistics now compatible with the Thermion Duo multispectral riflescope series.
This is the latest addition to a series of firmware updates rolled out for non-LRF models, with previous iterations made available for the Thermion 2 series, making Stream Vision Ballistics available on an even wider range of devices, and ensuring greater accuracy across some time-tested favourites.
