Product Name: Sokkia 726668 Single Prism Tilting Assembly Model NO.: AK13-1 Prism Diameter: 62mm Prism Precision: 3"-5" Packing: Soft Bag Canister Color: Red Target Color: Red Prism Accuracy: 3"-5" Trademark: OEM Transport Package: Standard Export Carton Specification: SGS Origin: Jiangsu, China HS Code: 90159000 Product Description Sokkia 726668 Single Prism Tilting AssemblyFeature:Model No.: AK13-1Effective diameter: 62mm.Offset: -30mm/0mm.Red canister, red with black target.Packing: Soft Bag.ACCURACY OF THE REFLECTORA circular prism is manufactured by cutting the corner from a solid glass cube. This creates three mutually orthogonal reflecting surfaces that reflect any light rays back towards their source.ANGULAR BEAM DEVIATIonThe angular difference between the entering and exiting beam is known as Angular Beam Deviation.A high deviation significantly reduces the returned signal strength and hence the measurement range.After manufacture, each prism is measured by Zygo inferometer to determine its beam deviation.Product:Workshop Show:
