Vision measuring systems are non-contact measurement machines used for inspecting various parts and components. This technology offers an efficient and precise alternative to traditional gauging methods.

Distributor of standard and customized vision testing equipment and vision inspection systems. Also provides coordinate measuring machines (CMM), arm type CMM's, comparators & hand tools as well as cleaning, calibration & technical support services.

Optical Comparators

Optic comparators is one of the more established measurement systems, requiring no PC software for operation and being relatively user friendly for many applications. Unfortunately, they do have some drawbacks, such as their limited measurement points and inability to measure angular dimensions.

Optical comparators usually consist of a 10x enlargement of a part drawing superimposed with a measurement chart on screen, containing grids for determining XY coordinate values, concentric circle marks for diameter or radius measurements, and radial mark scales to identify angles.

Comparators were traditionally used to measure angles by rotating their screen rings to measure them quickly, simply, and effectively - much like chart gages - making measurements quick, straightforward, and highly efficient. While more modern optical comparators feature digital rotary encoders for angle measurements - eliminating vernier scales from measurement processes altogether to further streamline and speed up measurements - many people are often amazed to discover that vision systems go far beyond being just comparators with automated inspection capabilities.

Microscopes

Microscopes are indispensable tools for precision manufacturers. Modern models boast more capabilities and ease of use than ever, such as new software, contrast techniques, and digital cameras that help create clearer images of parts and slides while making measuring them quicker and safer than ever.

A microscope consists of a frame for holding parts to be measured as well as lenses and detectors that convert light from objective lenses into electrical signals that allow computers to calculate dimensions based on edges measured with measuring devices.

Mitutoyo's Swift PRO vision measuring systems combine the accuracy and practicality of optical measurement with video measurement in one machine, making them ideal for shop floor applications that demand high throughput and ease of use.

Optical Imaging Systems

Vision measurement systems are computerized machines designed for real-time manufacturing applications that directly impact production lines (on-line applications). They can inspect for quality, identify defects and calculate measurements, as well as measure key dimensions within set tolerances of components or parts within their tolerances.

They can detect various product defects, from cosmetic flaws such as stains and spots to color clumps and scratches on surfaces or particle and imperfections in glass products. Furthermore, they can verify if a product was correctly manufactured by inspecting whether pills have been placed into blister packs correctly and verifying that seals on bottles have been correctly placed.

These optical measurement systems employ smart cameras equipped with CMOS sensors and intelligent optics that can be customized to suit specific application requirements. They're often combined with lighting or other components to form comprehensive inspection or measurement solutions.

Vision Testing Equipment

Vision measurement systems use computer-driven cameras to detect points on edges and surfaces for building 2D features. They can identify shapes such as lines, circles, ellipses and rectangles as well as geometric sizes like straightness and flatness as well as GD&T (Geometric Dimensioning and Tolerancing) metrics such as true position, parallelism and concentricity.

Vision inspection systems rely on three measurements: repeatability, accuracy and precision. Repeatability measures the consistency with which one operator performs inspections over time; accuracy refers to how close inspection results come to meeting an acceptable reference value; precision gauges how close results come to those values set forth as an ideal - something which can be accomplished through Gage Studies in which multiple operators make measurements using the same vision system and evaluate them against each other.

Other vision testing equipment includes visual field tests to measure how clearly objects can be seen, autorefractors for measuring refractive errors and slit lamp tests to diagnose eye diseases or conditions.
