Measurement/multi-sensor video systems

The L.S. Starrett Company has introduced a line of affordable Large-Format Multi-Sensor Video Measurement Systems ranging from 12" (305mm) to 50" (1273mm) of X-Y travel and 8" (200mm) of Z travel.

The new Large-Format Series offers increased speed at more than 25" of travel per second and greater accuracy to more than 4µm (157.5µin) to verify critical dimensions on complex, multi-featured parts. Models including the LF303, LF463, LF713, LF963 and LF1273 are available with vision, contact probe and laser scanning attachments.

The Large-Format systems can be configured to meet a variety of measurement needs in QC labs, research, engineering or manufacturing environments. Exceptional measuring accuracy / repeatability and outstanding throughput results are the outcome of unique design features such as transports that are driven by sophisticated, no-maintenance, balanced linear motors (versus drives) which are close-looped to precision scales in all three axes. The motors generate no heat and position to a small fraction of a micron. In addition, the new systems are the industry’s first in their category to offer porous carbon air-bearings for quiet, frictionless motion requiring no lubrication or maintenance and resulting in superb repeatability greater than 3µm (120µin) .

The moving axes of the systems are center-driven to reduce asymmetric thrust and eliminate the necessity of a separate (slave) scale, enhancing performance and measuring consistency. The systems also include a massive granite base and bridge, which provides exceptional mechanical and thermal stability. For optimum accuracy and efficiency, all axes feature “tape scales” in 1/10th µm (4µin) which are bonded directly to the granite structure of the machine. These scales are the most advanced on the market, featuring quasi-absolute encoder markings to streamline the “homing” sequence.

The Large-Format Video Systems offer high accuracy at E2=1.5+5L/1,000 and an Encoder Resolution of 0.1µm (4µin). A color optical system provides a zoom magnification ratio of 12:1 with programmable magnifications to 2000x via auxiliary lenses. An LED illuminator or triple output fiber-optic, ring light and co-axial illumination provides exceptional lighting.

The system includes a 22” widescreen and flat panel LCD display. For maximum operator performance, the Large-Format Systems include an adjustable ergonomic workstation including a compact control panel and standard keyboard
