Used KODAK 2A #155393 for sale

KODAK 2A optical comparator is an optical metrology device designed to compare a sample with a standard to determine if the sample meets the established requirements. It consists of an illuminated platform, a projection head, an arc arm, and a mirror. The illuminated platform is an inverted glass plate containing a metal ruler, which serves as a reference. The projection head is a metal box containing lenses and other components that project the specimen's image onto the metal ruler. The arc arm is a curved arm attached to the base of the projection head that allows the specimen's image to be positioned at various angles relative to the reference. The mirror is a small concave mirror that reflects light that is directed onto the specimen from a light source. 2A is primarily used for two-dimensional inspection, as it is able to measure the size, shape, position, and angular orientation of a specimen quickly and accurately. In order to inspect a specimen, the sample is placed on the illuminated platform and then the projection head is positioned so that the image of the sample is projected onto the metal ruler. The arc arm can then be adjusted to adjust the angle at which the image is projected. Once the position and angle are correct, the mirror is used to direct light onto the specimen at a specific angle and intensity, creating a diffused shadow that is compared to a reference template. The operator can then easily determine if any variance exists between the template and the specimen. KODAK 2A provides quick and accurate dimensional analysis of a variety of materials with a high degree of repeatability. It utilizes a special optical system that provides great tolerance, as well as focusing and clarity. Additionally, it can take measurements from samples of various sizes and shapes, including curved surfaces, making it an ideal tool for quality control and manufacturing operations.
