The Alpha Optics AO-4433/4435/4438 is the compact thermal imaging scope developed for 24 hours operation under any weather and environmental conditions. MicroLED technology transfers micrometer-scale LEDs into LED modules, resulting in remarkably high contrast with deep blacks, a wide colour gamut, high efficiency, fast response, wide viewing angle and the possibility of transparent and flexible (curved) displays.

The riflescope is made of high-grade construction materials that are lightweight, weatherproof and tough. Three modifications of objective lenses allow choosing perfect unit for your needs where 25 mm lens is designed for short range shooting, 50 mm lens model will be great for medium range missions, while 75 mm lens will become a perfect solution for long range aiming. Powered with two CR123 batteries, the AO-4433/4435/4438 provides up to 5 hours of continuous work. Optionally the capabilities of the device can be extended with Wi-Fi module, external video recorder, or monitor.
