HIKMICRO STELLAR 4.0 SX75L Thermal Riflescope

The STELLAR 4.0 SX75L pairs a 1280 × 1024, 12 µm thermal detector with a 75 mm F1.2 objective lens. Its sensitivity of less than 12 mK helps reveal subtle temperature differences, supporting detailed observation of animals and their surroundings. A quoted detection range of up to 3,600 metres provides considerable reach for scanning open ground.

A large 1.03-inch AMOLED display with 2560 × 2560 resolution presents the thermal image, while 3–30× magnification allows you to move between a broader view and closer inspection. Side-mounted focusing provides convenient adjustment, and the 8 mm exit pupil, 55 mm eye relief and adjustable dioptre help accommodate individual viewing preferences.

The scope incorporates HIKMICRO Image Pro 4.0, Zoom Pro, Sync Pro and the HIKMICRO Shutterless Image System (HSIS). Six color palettes, adjustable brightness and contrast, and warm or cool image tones let you tailor the display to the conditions. Picture-in-Picture provides a magnified viewing area while retaining the wider image.

An integrated laser rangefinder measures distances from 10 to 1,200 meters, with a stated accuracy of ±1 meter. Built-in ballistic calculation, five zeroing profiles and freeze zeroing provide further flexibility when configuring the scope for your setup.

On-board video and audio recording let you document time in the field, while recoil-activated recording automatically captures footage around a shot. Photographs and recordings are saved to 64 GB of internal storage, with a local album for reviewing files and hotspot connectivity for wireless use.

Power comes from two internal rechargeable lithium batteries and one replaceable, rechargeable 18650 battery. The stated operating time is seven hours at 25°C with the laser rangefinder switched on. USB-C power supports QC3.0 charging for the internal batteries; the external 18650 battery is charged separately using a battery charger.

With IP67 protection, a −30°C to +55°C operating range and a stated maximum recoil resistance of 6,000 J, the STELLAR 4.0 SX75L is built for demanding outdoor use.
