The Alpha Optics AO-2075 daytime binoculars are built from only the most exceptional quality glass to deliver a crisp and clear image. The glass features a special proprietary lens coating used in night vision technology to maximize light transmission for better performance in low light environments. Wide field of view reveals a larger portion of the horizon, allowing you to search more efficiently. Large 50 mm objective lenses have tremendous light-gathering ability. Multi-coated optics dramatically increase light transmission for brighter images with increased contrast and resolution. Large exit pupil provides maximum light during nighttime and low-light viewing sessions.
