Item Type: 3D Scanning Reference Point Markers_x000D_ Material: PET and reflective film_x000D_ Size: Inner Diameter: Approx. 6mm / 0.24in, Outer Diameter: Approx. 10mm / 0.39in_x000D_ Thickness: 0.15mm_x000D_ Performance: Highly reflective, strong adhesive_x000D_ Quantity: 3 Sheets(50pcs per sheet, 150pcs in total) 1SIZE AND QUANTITY: Inner diameter is 6mm, outer diameter for 10mm, each sheet contain 50 single point mark, possess high reflective brightness, tear resistant, waterproof and sunscreen, good ink absorption, repeatable fit 2WORKING PRINCIPLE: Reflective marking point with bright reflective film is on the surface of PET film with aluminum plated way adhesion to a layer of reflective glass microbeads, through the way of screen printing according to the specific size of the hollow printed circular reflection spot 3HIGH ACCURACY SCANNING: These markers are rigorously tested and validated to provide accurate and reliable data for applications such as 3D scanning, reverse engineering, metrology and inspection 4EASY TO USE AND RELIABLE: The marking is designed with adhesive foil, which is user friendly and easy to apply and remove. Alignment during scanning ensure excellent data and reliable reference points 5APPLICABLE SCENARIO: Used for 3D scanners in the field of motion information acquisition(such as three dimensional motion catch, three dimensional gait analysis, etc.), the markers can reflect the light emitted by the device (usually infrared light) reflected by the data device to receive, and the system processes the received data to achieve fixed point processing 6WIDE RANGE OF APPLICATIONS: Positioning markers are widely used in automotive, aerospace, machinery, manufacturing, power generation, electronics and education industries. Whether you are a professional user or an educational institution, can provide reliable support for your project3 x 3D Scanning Reflective Positioning Stickers(3 sheets, 150pcs in total)
