Detailed Product Description Detailed Parameters
Plastic surface is a smooth black surface. When plastic footprint is used to extract sheets and adhere to dust footprints, dust particles are adhered to the surface of plastic surface. When grazing incident light is used to illuminate the plastic surface, mirror reflection of incident light is produced on the plastic surface, while diffuse reflection of incident light is produced by dust particles. When the mirror reflection light is staggered, dust particles can be seen. The footprint pattern formed by grains is very bright, and the contrast of the pattern is far greater than the dust footprint extracted by ordinary pressure sensitive adhesive footprint tape.
