Cleaning camera sensors made easy. The sensor in your DSLR camera is perhaps the most important, and also most delicate, component of your entire photography tool set. Even the tiniest smudge or dust particle on the sensor can negatively affect the quality of your photos and videos. For years, many photographers and videographers have resorted to inspecting their images on a computer monitor, but Polaroid has a better solution: The Polaroid sensor loupe. Powerful 10x Magnification By magnifying your camera's sensor to 10 times its actual size, the Polaroid sensor loupe helps you locate any dust, debris or fingerprints - however small. This makes it easy for you to remove any photo-ruining elements from the sensor. Ultra-Bright 6-LED Array 6 ultra-bright LEDs are arranged in a circle around the rim of the Polaroid sensor loupe. For maximum illumination, the bulbs' set angle ensures that they are trained directly at the sensor when you position the loupe in front of it. Premium Optical Glass The Polaroid sensor loupe is constructed of premium materials. The lens itself is a high definition optical glass that is multicoated to reduce chromatic aberrations. The result is a crystal-clear, distortion-free view of your camera's sensor. 2 CR2032 Batteries Included The 6 embedded LEDs are long lasting and virtually never need replacing. They are powered by two single cell CR2032 batteries, which do need replacing from time to time. To get you started right out of the box, one pair is included.
