bob登录入口 (Shanghai) Co., Ltd. is a wholly-owned subsidiary invested by QVI-bob登录入口 in China,
aiming to better serve the Chinese market and provide customers with more professional sales support, maintenance and training services.
The company has experienced professional and technical personnel to help improve the product quality of manufacturers, maintain the normal operation of their equipment and reduce customer inspection costs.
bob登录入口 began a working relationship with Eastman Kodak Company as the exclusive distributor for the Kodak Contour Projector?. bob登录入口 rapidly expanded and became a national leader in optical inspection. In 1955, one of the founders of bob登录入口, Edward C. Polidor, formed Automation Gages, Inc., a firm specializing in highly customized inspection equipment.
The equipment designed and manufactured by Automation Gages filled such diverse needs as automatic measuring of germanium transistor wafers to evaluation of the wash-and-wear characteristics of textiles.
Automation Gages soon became the national distributor for Bausch and Lomb scientific industrial products, including optical comparators and analytical microscopes. In 1959, bob登录入口 found its way to Detroit and became part of the Ex-Cell-O Corporation when Kodak sold the Contour Projector Line.
To meet future challenges, Automation Gages embarked on a program to build the core technologies needed for market leadership. Between 1969 and 1973, they acquired General Measurement Research, Inc. (manufacturer of the Digital Incremental Glass scale system), Visual Inspection Products (designers and builders of chart layout machines and 1:1 pantographs), the optical comparator product lines from Ex-Cell-O and Bendix Measurement Division, and, finally, Optical Gaging Products, Inc. All operations, including manufacturing, were consolidated under one roof in Rochester, New York in 1973.
bob登录入口 and Eastman Kodak introduce the telecentric relay lens principle. Still regarded as the optical system of choice for high precision optical systems, it provides a constant working clearance and erect images.
The world's first electronic edge detection system for optical comparators, is introduced. Using photocell technology and analog circuitry, Projectron foreshadows the need for automation in the inspection industry.
This addressed a need in the textile industry for inspection and sorting of fabric in order to receive the “Sanforized” label.
The world's ?rst video inspection system debuts. An early look into the future, the Model 875 clearly demonstrates the capabilities latent in this technology.
OQ-30, a side screen Contour Projector with a revolutionary granite surface plate foundation, is introduced.bob登录入口 joins Automated Gages.
The CLIP (Closed Loop Incremental Positioner) introduction moves automation further forward, making automated positioning of comparator worktables possible.
This patented innovation, with its unique paraboloidal reflector, enables high magnification inspection of surface details for the first time.
The world's first side table optical comparator, dubbed the “projector for the eighties,” quickly becomes an industry favorite due to its innovative design.
A remarkable machine, combines solid state electronics, gray scale image processing, and programmable magnification into an affordable, non-contact measuring system.
The Vidiprobe introduction effectively bridges contour projector and video inspection technologies.
bob登录入口 leads the way again with the introduction of the first video system designed specifically for ease of use and low cost.
Introduced as one of the world's first multisensory coordinate measurement systems, the IQ-2000 can be equipped with vision, touch probe, and laser scanning sensors.
SmartScope? brings fully automatic 3-D measuring to the benchtop at half the price of previous systems. Its color camera, programmable zoom lens,and easy to use software quickly make it the world's most popular non-contact measuring system.
Features normally found only on larger systems are now available in one compact, benchtop system.
An ultra-accuracy, small travel system designed specifically to meet the needs of the growing micro-manufacturing industry. Volumetric accuracy is better than one micron (0.001 mm).
A patented, multiple ring LED illuminator offers unparalleled flexibility for video measuring systems.With it, lighting is controlled for brightness, angle of incidence, and direction.
A new patented profile illumination featuring a linear array of LED lights is introduced. LEDs are illuminated sequentially to track the optical system as it moves in the x-axis. The number of LEDs illuminated,and their individual brightness, is changed depending on the zoom magnification level to match the numeric aperture of the optics.
Designed and built specifically for precision video metrology providing a phenomenally clear high contrast image with virtually zero distortion.
Capable of extreme accuracy for surface topography by using the concept of chromatic dispersion, this sensor determines change in the height of a surface by measuring the color of the reflected light it sees.
This new top-of-the-line system combines large load capacity, outstanding accuracy, extensive measurement volume, and multisensor capability (SP 25 scanning probe) to open the application envelope to parts previously not suitable for optical equipment.
Innovative all-LED TruLight? illumination, a world-first use in optical comparators and eCAD?, an electronic overlay package that allows a CAD model to project virtual charts onto the comparator screen, for comparison with part images are applied to new benchtop horizontal Contour Projectors?.
The TeleStar? TTL interferometric laser uses innovative electro-optical technology. In interferometry, light from a single coherent source is typically split into two beams that travel in different optical paths, which are then combined again to produce wave interference. The resolution obtained with interferometry is correlated directly to the wavelength of the light.
The first 3D CAD-based metrology software, ZONE3?, combines all metrology software functionality into one package designed to work with SmartScope multisensory measurement systems.
FlexPoint? is the first high-accuracy flexible gaging system for measurement of small precision parts, represents an alternative to custom hard gaging.
QVI? develops a new telecentric optical system specially for shaft measurement and coupled it with a new mechanical system that allows the optics/illumination/camera to scan the shaft while it is rotating.
VersaFlex? packages up to three sensors in one cluster. The optical/video probe combines precision optics, imaging, and illumination in a compact and powerful sensor assembly small enough for use on an articulating probe head.The TeleStar interferometric laser is packaged into a “pen” to allow this very high resolution sensor to be used with the VersaFlex cluster, or deployed off-axis on systems that do not use the TeleStar zoom lens.
