The 5x30 Sensor Check Magnifier from Photographic Solutions offers 5x magnification with a 30mm lens diameter for looking at your camera's sensor to help you clean dust and debris. It features six LEDs to light up the area and better see your sensor. The Sensor Check also has adjustable focus for working with different sized cameras and sensors. The device itself will rest into the lens opening of most DSLR cameras and will pivot 45° to get out of the way for cleaning. It runs on the two included CR2032 batteries and comes with a zippered nylon pouch.
