HIKMICRO Stellar 4.0 SQ50L Thermal Riflescope 50 mm 640x512 with LRF







HIKMICRO Stellar 4.0 SQ50L Thermal Riflescope
The HIKMICRO Stellar 4.0 SQ50L combines the traditional appearance of a riflescope with advanced thermal imaging technology. Featuring a 640 x 512 thermal sensor, a powerful 50 mm F1.0 objective lens and an integrated laser rangefinder, this thermal riflescope is designed for detailed observation at extended distances.
With thermal sensitivity below 12 mK and a detection range of up to 2,600 metres, the SQ50L 4.0 delivers detailed thermal images even in challenging conditions. HIKMICRO's latest image processing technologies provide sharp, smooth and stable image reproduction.
High-Resolution Thermal Sensor with NETD Below 12 mK
The Stellar 4.0 SQ50L features a 640 x 512 thermal sensor with a 12 µm pixel pitch. Its high thermal sensitivity allows subtle temperature differences to be detected, even in conditions such as fog, rain or environments with limited thermal contrast.
The 50 mm F1.0 objective lens provides an excellent combination of detail recognition and long-range performance. A base magnification of 3.5x allows distant objects to be observed clearly without relying on additional digital magnification.
Image Pro 4.0, Intelligent Zoom and HSIS
The Stellar 4.0 series incorporates advanced image processing technologies designed to deliver clear, responsive and consistent thermal images.
- Image Pro 4.0: enhances image contrast, sharpness and the visibility of fine details.
- Intelligent Zoom: uses AI-assisted image processing to preserve image detail during digital magnification.
- HSIS: the HIKMICRO Shutterless Imaging System reduces image interruptions during automatic calibration.
- Sync Pro: minimises the delay between movement in the observed scene and its appearance on the display.
These technologies work together to provide a smooth viewing experience, particularly when observing moving heat sources.
Integrated Laser Rangefinder up to 1,200 Metres
The HIKMICRO Stellar 4.0 SQ50L is equipped with an integrated laser rangefinder (LRF) capable of measuring distances of up to 1,200 metres. This allows the distance to an observed object to be determined directly through the riflescope.
The device also features a ballistic calculation function. The availability and use of these functions depend on the selected settings and applicable local regulations.
Large 1.03-Inch AMOLED Display
The large 1.03-inch AMOLED display provides a spacious viewing image with excellent contrast. Its generous display area makes it easier to distinguish fine details and contributes to a comfortable viewing experience.
Adaptive display brightness can automatically respond to changing lighting conditions. This function must first be enabled in the device menu.
Traditional Design and Comfortable Viewing
The Stellar 4.0 retains the familiar appearance of a conventional riflescope, featuring a 30 mm main tube diameter. The focusing and magnification controls are positioned towards the rear of the device for convenient operation.
With 55 mm eye relief and an 8 mm exit pupil, the riflescope offers a comfortable viewing position. Its simplified menu can be customised to suit individual preferences.
