Thermal Imaging & Detection
The 640 × 512 thermal sensor combines 12μm pixel pitch with sub-12mK sensitivity to reveal fine temperature differences across complex backgrounds.
The 50mm F1.0 lens provides a detection range of up to 2,600m under suitable conditions, making the SQ50LR suitable for observation across open fields and varied terrain.
Detection range describes the ability to detect a heat source, rather than guaranteed identification at that distance.
Integrated Laser Rangefinder & Ballistics
The SQ50LR incorporates a Class 1 laser rangefinder within the objective assembly, providing measurements from 10m to 1,200m with a stated accuracy of ±1m.
The integrated ballistic calculator uses distance information alongside configured ballistic data to provide an aiming reference.
Users must verify ballistic settings and zeroing for their particular equipment.
Rail Mounting & Compatibility
The SQ50LR features an integrated rail mounting interface instead of a conventional 30mm mounting tube.
This design allows installation using a suitable compatible rail mounting system and avoids the need for conventional scope rings.
Please note: The integrated rail is part of the riflescope, but a compatible rifle-specific mounting interface may be required separately. Confirm the rail standard and mounting compatibility before ordering.
For a conventional 30mm tube suitable for scope rings, the Stellar 4.0 SQ50L is the corresponding alternative.
Image Pro 4.0 & Shutterless Imaging
HIKMICRO Image Pro 4.0 enhances image detail, contrast and noise reduction, while intelligent zoom processing helps retain clarity at increased magnification.
HSIS shutterless technology maintains continuous thermal viewing without routine shutter calibration interruptions.
Sync Pro supports responsive, low-latency viewing.
Display, Magnification & Controls
The 1.03-inch AMOLED display has a resolution of 2560 × 2560 pixels, providing a detailed viewing image through the eyepiece.
Magnification ranges from 3.5× to 28×, adjusted using the familiar rear magnification ring.
The scope also features a side focus control, 55mm eye relief and an 8mm exit pupil for comfortable viewing.
Battery & Charging
The Stellar 4.0 SQ50LR combines two internal rechargeable lithium batteries with a replaceable external 18650 battery.
HIKMICRO specifies up to 9.5 hours of continuous operation at 25°C with the laser rangefinder enabled.
The USB-C connection charges the internal battery system. The removable 18650 battery must be charged using the supplied external battery charger.
Actual runtime varies according to temperature and operating settings.
