Optical Projection Comparator

Optical Projection Comparators are instruments used in physical properties testing and inspection. They belong to the supply class of Physical Properties Testing And Inspection and are categorized under the supply group of Instruments And Laboratory Equipment.

Optical Projection Comparators are used to measure and inspect the dimensions, contours, and surface features of various objects. They use optical magnification and projection systems to enlarge the image of the object being inspected, allowing for precise measurements and comparisons.

These comparators typically consist of a light source, a projection lens, a stage for holding the object, and a measuring system. The object is placed on the stage, and the light source illuminates it. The projection lens then magnifies the image of the object and projects it onto a screen or a measuring reticle. The measuring system allows for accurate measurements of the dimensions and features of the object.

Optical Projection Comparators are commonly used in industries such as manufacturing, quality control, and research and development. They are particularly useful for inspecting small parts, such as machined components, electronic circuits, and precision tools.

Overall, Optical Projection Comparators are essential instruments in physical properties testing and inspection, providing accurate and reliable measurements for various applications.
