Video measuring machines generally provide three types of lights: surface lights, contour lights, and coaxial lights.
As the measurement technology becomes more and more mature, the measurement software can control the light in a very flexible way. For different measurement workpieces, the measurement personnel can design different lighting schemes to obtain the best lighting effect and make the measurement data more accurate. accurate.
The choice of light intensity generally needs to be determined based on experience and observing the clarity of the captured image. However, this method has a certain degree of arbitrariness, even for the same measurement scene, different operators may set different intensity values. The fully automatic video measuring machine of HanDing Optical can automatically turn on the light function, and can determine the best light intensity according to the characteristic of the best light brightness and the richest image details.
For the contour light and coaxial light, since there is only one incident direction, the measurement software can adjust the brightness of the light. The contour light and the lens are located on different sides of the workpiece, and are mainly used to measure the outer contour of the workpiece. The coaxial light source is used for the measurement of workpieces with high reflectivity surfaces, such as glass, and is also suitable for the measurement of deep holes or deep grooves.
