Vexcel Imaging VX 4000 HT Image Scanning System

VXServices' Vexcel Imaging Scanning Systems have been recognized worldwide for years as products of choice for professionals in the Softcopy Photogrammetry, Geographical Information System and Intelligence/Reconnaissance application domains. The VX4000HT family adds speed and upgradability to the tradition of accuracy and reliability established by the VX3000 product group. The system's interactive and real-time control over radiometry, resolution and image areas to be scanned — when combined with programmable LUTs and image processing functions — make the VX4000HT the ultimate image capture system.

Image oriented users all over the world have found the VXServices' family of scanning systems to be ideal instruments for enabling applications including othrophoto production, softcopy photogrammetry and image exploitation. The VX4000 family is the most recent addition to the renowned line of VX scanners. The VX4000HT adds speed and increased productivity to a system tried and proven for years in the field. The image format scan area of 254 x 508 millimeters facilitates the scanning of a broad range of film types. System features, when combined with VXServices' programmable Automatic Film Device (AFD) and Auto-Dodging, mark a major breakthrough in scanning productivity and price/performance.
