Pixfra® Cetus C225 Thermal Riflescope

The Pixfra Cetus C225 is a compact thermal riflescope built around a 256 × 192 VOx detector with NETD sensitivity of ≤18 mK. Its 25 mm F1.0 objective lens provides 3.5× native magnification and a manufacturer-rated detection range of up to 1,300 m. PIPS 3.0 image processing, five customizable zeroing profiles, and recoil-activated recording provide the essential functions required for hunting and observation in low-light and adverse weather conditions.

VOx Detector and 25 mm Objective Lens

The uncooled VOx detector combines a 256 × 192 resolution with a 12 μm pixel pitch. Its thermal sensitivity helps preserve usable target and background detail in fog, rain, vegetation, and other conditions with reduced thermal contrast.

The 25 mm F1.0 objective lens provides 3.5× native magnification and a field of view measuring 12.4 × 9.2 m at 100 m. The manufacturer specifies a detection range of up to 1,300 m.

PIPS 3.0 Image Processing

PIPS 3.0 processes the detector output to improve image definition and retain useful detail when digital magnification is applied. The digital zoom can be increased progressively up to 8×.

Picture-in-picture enlarges the central portion of the image while retaining the wider scene in the main display. Additional viewing tools include hot spot tracking, defective-pixel correction, multiple flat-field correction modes, and six selectable color palettes.

OLED Display and Combined Controls

The thermal image is displayed on a 0.32" OLED screen with a resolution of 800 × 600 px. A 45 mm eye relief provides suitable viewing distance when the scope is mounted on a firearm, while adjustable diopter correction allows the eyepiece to be adapted to the user’s eyesight.

The combined wheel-and-button layout keeps the primary functions accessible without requiring a large number of separate controls.

Customizable Zeroing Profiles

The Cetus C225 can store five zeroing profiles with selectable reticle patterns and colors. Profiles can be added, renamed, deleted, and organized into different zeroing-distance groups.

Compatible settings and zeroing functions can also be managed through the Pixfra Outdoor mobile app.

Recoil-Activated Recording

The recoil-activated recording function uses an impact sensor to save footage from 15 seconds before to 15 seconds after a shot. This captures the relevant sequence without requiring recording to be started manually before every shot.

The scope can also capture photographs and conventional video with sound. Files are stored in the 64 GB internal memory and can be reviewed on the device or transferred to a compatible smartphone through the built-in Wi-Fi connection.

Replaceable 18650 Battery

Power is supplied by a replaceable rechargeable 18650 battery. The press-to-release battery cover allows the battery to be changed quickly without tools.

Runtime is at least five hours at 25 °C with Wi-Fi switched off. The USB-C port also supports operation from a compatible external power source.

Magnesium-Alloy Housing

The magnesium-alloy housing provides structural rigidity while keeping the riflescope’s weight to approximately 520 g. Its IP67-rated construction protects the device against dust and temporary water immersion and supports use across a wide operating temperature range.

The scope is rated to withstand recoil acceleration of 1,000 g for 0.4 ms. A quick-detach mounting system is included for installation on a compatible firearm rail.
