The Medium, 20mm Digital Duster Refill Kit from Delkin helps remove spots you can't see but that can affect your pictures. Dirt comes from many sources and it must be removed in a safe and effective way or your images will show this debris.
Four common types of contaminants can get on your image sensor: metallic, fiber, organic and silica/quartz particles. Only the SensorScope system addresses all four types of material and the proper way to remove them safely.
Medium Sensor Wands are designed to fit sensors measuring 20mm on the short side. This kit includes a LensPen. The LensPen is a handy tool to have when it comes to cleaning optics such as lenses, binoculars and telescopes. The retractable brush removes small spots with its non-liquid cleaning element. It never dries out and is safe and easy to use.
