The HIKMICRO Stellar 4.0 SX75L Thermal Riflescope combines an ultra-high-resolution 1280 × 1024 thermal sensor with a large 75mm F1.2 objective lens and integrated 1,200m laser rangefinder, delivering exceptional image detail for demanding long-range thermal observation.
With sub-12mK thermal sensitivity and a detection range of up to 3,600 metres, the SX75L offers advanced thermal performance across open countryside and challenging terrain. Its high-resolution sensor captures four times as many pixels as a 640 × 512 thermal detector, helping preserve image detail at increased magnification.
HIKMICRO's Image Pro 4.0 processing, intelligent zoom and HSIS shutterless imaging technology work alongside a large 1.03-inch 2560 × 2560 AMOLED display. Traditional side focus and rear magnification controls provide familiar riflescope handling, while the integrated ballistic calculator and rechargeable battery system support extended field use.

1280px Thermal Imaging & Detection
The SX75L features a 1280 × 1024 thermal detector with 12μm pixel pitch and sub-12mK sensitivity, delivering detailed imaging even where small temperature differences are present.
Its large 75mm F1.2 objective lens provides a manufacturer-rated detection range of up to 3,600m under suitable conditions.
The high-resolution sensor helps retain fine detail at higher magnification, while the relatively wide field of view supports effective scanning across open terrain.
Detection range refers to detecting a heat source rather than guaranteed identification at that distance.
Integrated Laser Rangefinder & Ballistics
The SX75L features an integrated Class 1 laser rangefinder positioned within the objective assembly, preserving the traditional appearance of the riflescope.
It measures distances from 10m to 1,200m with a stated accuracy of ±1m.
The integrated ballistic calculator can use distance measurements and configured ballistic information to provide an aiming reference.
Ballistic settings and zeroing must be verified for the equipment in use.
30mm Tube & Mounting Compatibility
The Stellar 4.0 SX75L features a standard 30mm mounting tube, allowing installation using suitable 30mm riflescope rings.
30mm scope rings are required and are not included in the standard package.
Ring height and mounting clearance should be checked carefully because of the large 75mm objective lens.
For an integrated rail mounting interface instead of conventional rings, the Stellar 4.0 SX75LR is the corresponding alternative.
Image Pro 4.0 & Intelligent Zoom
HIKMICRO Image Pro 4.0 improves thermal image detail, contrast and noise reduction through advanced image processing.
Intelligent zoom helps preserve clarity at increased magnification, while HSIS shutterless imaging provides continuous viewing without regular shutter calibration interruptions.
Sync Pro technology supports responsive, low-latency viewing.
Display, Magnification & Controls
The 1.03-inch AMOLED display features a 2560 × 2560 resolution for detailed viewing through the eyepiece.
Magnification ranges from 3× to 30×, adjusted using the rear magnification ring.
A side focus control, 55mm eye relief and 8mm exit pupil provide familiar riflescope handling and comfortable viewing.
Battery & Charging
The Stellar 4.0 SX75L combines two internal rechargeable lithium batteries with a replaceable external 18650 battery.
HIKMICRO specifies up to 7 hours of continuous operation at 25°C with the laser rangefinder enabled.
The USB-C connection charges the internal batteries. The removable 18650 battery must be charged using the supplied external charger.
Actual runtime varies according to temperature and operating settings.
Recording & Additional Functions
