Whether or not the device is high performance, one of the items you should check is that the device has less dead area. If it has much dead area, then the data may be destructed by noises and defect even if the measuring is accurate. However, HEW-250 has a CCD camera on the center and a slit laser on each side. Scanning from both sides enables to acquire the data of areas that are difficult by one-side scanning.
When you do 3D measuring, you need lasers and cameras. However, it is important where and how you put the device and the object and from which angle you measure. HEW-250 is made compact and light in weight so that it can be used with various measuring tools. By using tools such as a revolving stage and up-down moving stage, it is able to measure the object from four sides and different angles.
VOXELAN is based on its own measuring principle, which is accumulated its know-how for 13 years. VOXELAN is made with precision, and various countermeasures have been done for noises. VOXELAN will not be disturbed by uneven color paint on subjects or sunlight by using optical cutting method. Since it has high stability, only the adjustment before delivery will be needed and no adjustment or maintenance are required every time you measure.
