The Alpha Optics AO-1234/1334 multipurpose night vision monocular is a high-performance modular night vision device. Smooth and ergonomic design makes it an ideal choice for use by law enforcement, military or civilians for any nighttime operations. The Alpha Optics AO-1234/1334 can be hand-held, head-mounted, helmet-mounted, or weapon-mounted Night Vision System that enables walking, driving, weapon firing, short-range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. Compatible with most IR laser aiming/illuminating devices, this model defines multi-mission versatility. Each unit allows for vertical adjustment (by using head straps), fore-and-aft adjustment, objective lens focus, and eyepiece focus and equipped with an Infrared light-emitting source. The Alpha Optics AO-1234/1334 utilizes the principle of intensification of the residual light which is reflected from the surrounding objects. IR has standard and flood option allowing users to focus the IR light source from 20 degrees to 40 degrees providing a flood IR effect.

The optical system of the Alpha Optics AO-1234/1334 consists of an objective lens, an Image Intensifier Tube and an eyepiece. Even under unsteady brightness conditions, Automatic Brightness Adjustment System always keeps the IIT brightness level constant. The Automatic Protective System controls the existing illumination level through the photo receiver. If the illumination level surpasses 100-300 lx for the following 10 seconds, the Monocular will shut off automatically.

The eyepiece incorporates several LED indicators:

- Red - serves as an IR Illuminator Indicator and a Battery Low Indicator at a time

- Green - serves as an Excessive Brightness Indicator.

If the bright light remains unchanged for over 10 seconds after the indicator turns on, the Monocular will automatically shut-off.
