The HIKMICRO Stellar 4.0 SX75LR Railed Thermal Riflescope combines an ultra-high-resolution 1280 × 1024 thermal sensor, a large 75mm F1.2 objective lens and an integrated 1,200m laser rangefinder in a dedicated rail-mounted configuration.
With sub-12mK thermal sensitivity and a detection range of up to 3,600 metres, the SX75LR is designed for detailed long-range thermal observation. Its high-resolution sensor provides four times the pixel count of a 640 × 512 thermal detector, helping retain fine image detail when viewing distant heat signatures.
HIKMICRO's Image Pro 4.0 processing, intelligent zoom, HSIS shutterless imaging and large 2560 × 2560 AMOLED display combine to provide clear, continuous thermal viewing. The integrated ballistic calculator, traditional riflescope controls and rechargeable battery system complete this advanced thermal riflescope.

1280px Thermal Imaging & Detection
The SX75LR uses a 1280 × 1024 thermal sensor with 12μm pixel pitch and sub-12mK thermal sensitivity to reveal fine temperature differences and detailed heat signatures.
The large 75mm F1.2 objective lens provides a manufacturer-rated detection range of up to 3,600m under suitable conditions.
Its high-resolution sensor helps preserve detail at higher magnification, making it particularly suitable for observing distant subjects across open terrain.
Detection range refers to detecting a heat source, not guaranteed identification at that distance.
Integrated Laser Rangefinder & Ballistics
The SX75LR incorporates a Class 1 laser rangefinder within the objective assembly, providing distance measurements from 10m to 1,200m with stated accuracy of ±1m.
The integrated ballistic calculator uses distance measurements and configured ballistic information to provide an aiming reference.
Ballistic settings and zeroing must be checked for the individual equipment configuration.
Integrated Rail Mounting & Compatibility
The Stellar 4.0 SX75LR features an integrated rail mounting interface instead of a conventional 30mm mounting tube.
This configuration is designed for use with a suitable compatible rail mounting system, providing an alternative to traditional riflescope rings.
30mm scope rings are not suitable for this model. A compatible rifle-specific mounting interface may be required separately.
The integrated rail is part of the riflescope. Confirm the rail standard and mounting compatibility before purchasing.
For a conventional 30mm tube, the Stellar 4.0 SX75L is the corresponding alternative.
Image Pro 4.0 & Shutterless Imaging
Image Pro 4.0 improves thermal image detail, contrast and noise reduction through advanced processing.
Intelligent zoom helps retain clarity at increased magnification, while HSIS shutterless technology provides continuous 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 detailed viewing through the eyepiece.
Magnification ranges from 3× to 30× and is adjusted using the rear magnification ring.
The riflescope also features a side focus control, 55mm eye relief and an 8mm exit pupil.
Battery & Charging
The SX75LR 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 is charged using the supplied external battery charger.
Actual operating time depends on temperature and enabled functions.
