OGP 20" Contour Projector Advances Comparator Technology While Delivering Proven Performance

Optical Gaging Products (OGP®) announces a technological innovation for its popular floor model 20" Horizontal Contour Projector®, the QL-20(TM) - a high brightness, long life, low energy LED profile light.

The latest QL-20 features innovative LED TruLight(TM) illumination, a world-first use in optical comparators. A high-brightness monochromatic green TruLight LED profile light is standard on all new QL-20s. TruLight LEDs offer variable intensities for optimal lighting at any magnification, and provide tens of thousands of hours of service while consuming only a fraction of the energy required for traditional illuminators.

The QL-20 features a generous 20" (508 mm) diameter screen, with a high capacity worktable to handle a broad range of parts. Its small footprint and vertical design allows large screen inspection in a relatively small floor space - less than 17 ft2. QL-20 offers large, bright images on a flat field screen for reduced operator eyestrain. Screen images are upright and unreversed, reducing visual confusion and aiding productivity.

QL-20 ergonomics are excellent. Controls are in natural positions, easily at hand for fatigue-free operation. The bright screen and digital readout displays are located conveniently at eye level, making it easy to visually scan back and forth between them. The in-line design of the worktable provides operators with easy access to mounted parts and fixtures.

Like all OGP Contour Projectors, QL-20 optics are of the highest quality. Lenses are truly telecentric in design, ensuring image accuracy and an image size that does not change with the focus position.

QL-20 includes an extensive list of standard features. The integral Geometric Measuring Processor with easy-to-read dual LCD displays and easy-to-reach shop-hardened keypad provides extensive tools for a number of geometric measurements. Automatic lens magnification sensing provides for error-free measurement scaling with every magnification change. The heavy duty, high precision 32" x 8" (813 x 200 mm) nickel plated worktable can easily support 550 lbs (250 kg). DC servo variable-speed motor drive with joystick control delivers smooth, quiet, fast worktable motion.

Even with such a large range of standard features, options are available. OGP Projectron(TM) internal automatic edge detection ensures repeatable measurements from operator to operator. The worktable provides ±7½° of helix motion. Automate the QL-20 with software packages including eChek(TM) metrology software and SmartReport® powered by QC-Calc(TM) report writer. Or use eCAD(TM), a new electronic overlay package that allows a CAD model to project a profile tolerance band onto the comparator screen. With eCAD, profile tolerance bands may be exaggerated and coupled to the part image for semi-automatic inspection, virtually eliminating the need for traditional overlay charts.

QL-20 will be featured at IMTS 2010, in OGP Booth E-5525. For additional information on QL-20 or any of the OGP metrology solutions, contact Optical Gaging Products, Inc. at (800) 647-4243, or email at
