  • Page 4 The SP2 beam scan camera and software is designed to facilitate observing and setting the mode of the YAG laser in the SP2. The system consists of a Mightex CCD camera which has been fitted with a high Optical Density (OD) filter. A mounting bracket allows the camera to be mounted in the position normally occupied by the YAG power monitor on the SP2.
  • Page 5 MAXIMUM of 70mW only under certain conditions, which are unspecified. Operation of the camera on the SP2 with any neutral density filter having an OD of less than 2 will void the warranty of the product. The Measured leakage should be between 80 –...

    If the above tests show that the SP2 YAG laser beam is in a satisfactory mode, no further adjustments are needed. Upgrades to the Visulux software are planned in the future to allow for continuous logging of the data, and this may be useful while collecting data with the SP2.

  • Page 11 Start the YAG laser and observe the laser beam profile. For SP2 instruments SN 007 and above, insert a 5/64” ball driver into the access hole. SP2 instruments below this serial number require a 1/8” ball driver. It can be useful to use a flashlight to look into the access hole and locate the position of the adjustment screw.
