Touch-compatible privacy filter works simply for 13.5" Microsoft Surface Book (landscape) to help protect your screen from everyday scratches and dust, and help keep the information displayed on them private. This custom-cut privacy filter gives your high-resolution screen side view protection from visual hackers. Microlouver technology delivers effective "black out" privacy from side views outside the 60-degree viewing angle and reduces 35 percent of blue light transmission from the display. Ultra-thin and ultra-responsive to the touch, this privacy filter provides privacy and consistent touch responsiveness without getting in the way of using your device. Satin-like matte finish is smooth to the touch. The frameless, scratch-resistant privacy filter with 3:2 aspect ratio is easy to attach with attachment strips, remove and clean. Viewing dimensions are 12-1/8" x 8-1/2" (308mm x 216mm).
