HIKMICRO STELLAR SX75L 4.0 1280 Thermal Riflescope with Laser Rangefinder

The HIKMICRO STELLAR SX75L 4.0 is a high-performance thermal riflescope designed around a 1280 × 1024 thermal sensor and a large 75mm F1.2 objective lens. Combining detailed thermal imaging with an integrated laser rangefinder and ballistic calculation, it brings observation, distance measurement and supporting shooting functions into a single unit.

Its traditional riflescope-style form features a 30mm main tube, side-focus control and a rear magnification ring. A high-resolution AMOLED display and HIKMICRO's advanced image-processing technologies are designed to provide a detailed, comfortable viewing experience.

High-resolution 1280 × 1024 thermal sensor

At the heart of the STELLAR SX75L 4.0 is an uncooled VOx thermal detector with a resolution of 1280 × 1024 pixels and a 12μm pixel pitch. This high-resolution sensor provides a detailed thermal image, helping users distinguish features in a scene.

The detector has a manufacturer-specified thermal sensitivity of less than 12mK NETD and operates at a 50Hz frame rate. High thermal sensitivity helps the device register subtle temperature differences, including in challenging environmental conditions.

75mm F1.2 lens for long-range detection

The 75mm F1.2 objective lens is designed for long-range thermal observation. HIKMICRO specifies a detection range of up to 3,600 metres, although actual detection and identification distances depend on the target, weather, background and viewing conditions.

The SX75L offers 3.0–30.0x magnification. Its field of view is approximately 21.2 × 17 metres at 100 metres, giving a useful reference for understanding the viewing area at distance.

Integrated laser rangefinder

The SX75L 4.0 incorporates its laser rangefinder within the lens assembly, preserving a conventional riflescope-style profile. The rangefinder has a specified maximum measuring distance of 1,200 metres, with a stated measurement accuracy of ±1 metre under suitable conditions.

Distance measurement is complemented by the built-in ballistic calculation function. This can provide useful range-related information when the device has been configured with the appropriate ballistic data. Results depend on correct setup and the ammunition, rifle and environmental information entered.

2560 × 2560 AMOLED display

The 1.03-inch AMOLED display has a resolution of 2560 × 2560 pixels. It presents the thermal image through the eyepiece, with a range of viewing palettes and image adjustments available to suit different conditions and user preferences.

The SX75L also features an 8mm exit pupil and 55mm eye relief. Dioptre adjustment from -5D to 5D helps users adapt the view to their eyesight.

Image Pro 4.0, Zoom Pro and shutterless imaging

HIKMICRO's image-processing technologies are designed to improve the viewing experience:

• Image Pro 4.0: enhances image detail and contrast.

• Zoom Pro: helps maintain image clarity as magnification increases.

• HSIS shutterless technology: reduces interruptions associated with conventional shutter-based thermal calibration.

• Sync Pro: supports responsive image processing for a smooth viewing experience.

The scope also includes adjustable image brightness, contrast and tone, alongside multiple thermal colour palettes.

Recording, connectivity and practical controls

The STELLAR SX75L 4.0 supports onboard video recording, audio recording and snapshot capture. Recoil-activated recording is also available, and the built-in 64GB storage provides space for saved media.

Additional functions include picture-in-picture (PIP), Hot Track, hotspot connectivity and five zeroing profiles with Freeze Zeroing. Wi-Fi connectivity allows compatible use with the HIKMICRO Sight app.

Side-focus and magnification controls retain a familiar layout for users accustomed to conventional riflescopes.

Dual-battery power system and durable construction

The SX75L uses two internal rechargeable lithium batteries alongside a replaceable, rechargeable 18650 battery. HIKMICRO specifies up to seven hours of operation at 25°C with the laser rangefinder active; actual runtime varies with usage and conditions.

The device has an IP67 protection rating and a specified recoil resistance of up to 6,000J. It is designed to operate in temperatures from -30°C to 55°C.

Technical specifications

Specifications are based on HIKMICRO's UK product information and retailer technical listings. Detection range and battery runtime are manufacturer-stated figures; real-world performance will vary with conditions.
