Installation (AB-) . The camera adapter is mounted between the scan head's beam entrance and the laser flange (see Fig 1). IftSH Working principle ^fc&, CCD&^£ «CCD^X#o Illumination light reflected from the surface of the workpiece pass through achro matic F-theta, galvo scanner,beam splitter,CCD lens to reach the CCD sensor. Adjust beam splitter position to compensate the error of machinng and assembly to ensure the optical path of the laser and reflected light coxial.Make the laser coi ncides with the CCD image detection point.

For example, 160mm lens,CCD camera focus is 135mm, CCD target surface size of 1/2"(6.4mm*4.8mm), the field of view is 20.4mm*15.3mm(see table) Coaxial CCD adapter tuning method and steps Adjust the galvanometer height, find the galvanometer focus position. 2, sa#«i>x®fra+^So Mark the crosshair. 3, £CCD£MMIo Adjust the focus ring 4 (CW or CCW), to the camera showing a clear image. 4, Locking camera. 5, »«5, */«#■««, ^CCD®|^X^ + «Xft-^o Loosen screw 5, CW or CCW adjusting camera, to make the orientation of the image the same as the crosshairs. 6, «^M5o Lock screw 5. ^^2, 3S^^^^ + ^^^CCD@|+^t'^'^S^o Observe the CCD image crosshair and the marked crosshair position. If the two crosshair does not coincide with each other need to open the protective cover, tuning the knob 2 and knob 3. Take © (see Figure 3) as an example, When the knob 2 is adjusted, the center of the image will move left and right diagonally.When the knob 3 is adjusted, the center of the image will move up and down diagonally .Tuning knob 2 and 3 to make the image crosshair coincide with the marked crosshair. After tuning restore the cover.
