Optical Gaging Products (OGP®), a division of Quality Vision International (QVI®), now offers its large measurement volume SmartScope® Quest 800 multisensor dimensional measurement system to the metrology marketplace. With its generous 790x815x250 mm XYZ measurement volume and available 300 or 400 mm extended Z axis, SmartScope Quest 800 accurately measures very large parts or large arrays of smaller fixtured parts. For measurement stability, the Quest 800 optics/sensor head is mounted on a stable granite bridge over the worktable and moves only in the X and Z axes, while the worktable itself moves underneath in the Y axis. The innovative 10:1 TeleStar® telecentric zoom lens provides high-level optical performance and accurate video metrology. SmartScope Quest 800 is fully multisensor-capable with available touch trigger probe, SP25 continuous contact scanning probe with PH10 motorized probe head, patented on-axis TeleStar Plus interferometric TTL laser or off-axis DRS™ laser, and micro-probes to measure fragile parts or extremely small part features. SmartScope Quest 800 is available with QVI’s ZONE3® premium CAD-based 3D metrology software. ZONE3 features a clear, simple user interface, and its kinematic model simulates the machine, part, fixtures, and measuring sensor, updated in real time. Built-in productivity maximizing tools, integrated GD&T functionality, and visual validation of measurement intent offer speed and power to the measurement process. ZONE3 supports simultaneous use of multiple sensors, including multiple lasers, making appropriate tools available for complex measurement tasks. ZONE3 represents the state-of-the-art in 3D metrology software.
