HikMicro Alpex 4K Day/Night Riflescope FAQs

What magnification range does the HikMicro Alpex 4K offer?

The Alpex 4K provides a native magnification range from 3.5x up to 28.0x using continuous digital zoom. This allows smooth transitions between lower magnification for situational awareness and higher magnification for target identification. The 4K sensor helps maintain usable detail even at higher zoom levels.

How does the adjustable aperture benefit day and night use?

The 50 mm lens features an adjustable aperture from F1.2 to F2.5, enabling the user to control light intake manually. This helps optimise image quality in bright daylight as well as low-light night conditions. Adjusting the aperture can reduce glare or improve contrast depending on ambient light.

Is the Alpex 4K suitable for both daytime and nighttime hunting?

Yes, the scope is designed for true day and night operation using available ambient light. It delivers full-colour imagery during the day and switches to black-and-white viewing at night. This dual-mode functionality makes it suitable for varied hunting scenarios.

What type of display does the Alpex 4K use?

The riflescope uses a 0.49-inch OLED display with a resolution of 1920 × 1080. OLED technology provides high contrast and fast response times, contributing to clear image presentation. The enlarged viewfinder improves overall viewing comfort.

How is the scope powered and what is the battery life?

Power is supplied by two internal rechargeable lithium batteries combined with one external replaceable 18650 battery. This hybrid setup delivers up to 11 hours of continuous operation at 25 °C with hotspot features disabled. Charging and external power are supported via a USB-C interface.
