The Sensor Inspection Loupe Kit provides you with the necessary tools to inspect your D-SLR camera sensor for dust. Compact in size and flexible in use. With the 3 different Jewelers Loupes, you get 4X, 5X and 10X magnifications. The 10X is great for seeing those very small particles of dust where 5X is a medium magnification and the 4X gives you a little room where you can actually view while cleaning. The high powered Photon Micro-Light attaches to the Jewelers Loupes with Velcro (included).
