Package includes 2 sheets of scanning markers (1 sheet contains 72 pieces). Total 144 markers. Product overview These reflectivity scanning markers are peelandstick PET film dots designed to simplify setup for 3D scanning and optical surveying. Each round marker has a 6 mm diameter and a thickness of 0.10 cm, providing a compact, visible target for scanner detection in both indoor and outdoor environments. Multi color markers allow easy differentiation of reference points. Key benefits Quick setup: peelandstick application saves time on site and reduces the need for fixture adjustments. Reliable detection: reflective surface and 6 mm diameter ensure precise identification by most 3D scanners and optical measurement systems. Consistent calibration support: serve as dependable auxiliary points for positioning and calibration during optical surveying and inspection tasks. Material durability: made from PET reflective film for stable reflectivity across multiple uses. Compact size: 0.60 x 0.60 x 0.10 cm (0.24 x 0.24 x 0.04 in) markers are small enough for finedetail work yet large enough for accurate detection. Features and specifications Quantity: 2 sheets, 72 markers per sheet, total 144 markers. Marker diameter: 6 mm. Thickness: 0.10 cm. Material: PET reflective film. Color: Multi. Application: Designed for precision industrial and consumer 3D scanning, reverse engineering, meteorological detection, optical surveying, and general calibration tasks. How it solves common problems Reduces setup time and manual alignment by providing immediate, visible reference points. Improves scan accuracy where natural surface features are insufficient or inconsistent. Allows consistent calibration across repeated measurements or multiple devices. Practical use scenarios Reverse engineering: place markers on complex parts to create reliable reference points for accurate surface reconstruction. Optical surveying and calibration: use as auxiliary targets to align instruments and verify positional accuracy during site surveys. Field and lab scanning: apply markers to structures, prototypes, or terrain for consistent detection during outdoor meteorological monitoring or indoor inspection work. What to expect in use Easy peelandstick application on flat or slightly curved surfaces. Distinctive colors help organize reference points for multistep scans. Reliable reflectivity in typical indoor and outdoor lighting conditions when used with compatible scanning systems. Compatibility note Markers are suitable for use with most professional and consumer 3D scanners, photogrammetry setups, and optical surveying equipment that utilize reflective reference targets. Contents recap 2 sheets x Scanning markers (72 pieces per sheet). Total 144 reflective PET film dot markers, 6 mm diameter, multi color.
