Page 9: Safety
1.5 Safety The IBP-YAG is intended for use with high power YAG lasers. Precautions must be taken to prevent accidental exposure to reflected and scattered beams. The safe use of high power lasers requires that everyone near a laser be aware of the dangers involved. 1.5.1 Precautions for safe operation •... -
Page 10: Chapter 2 Setup And Operation
Chapter 2 Setup and Operation 2.1 Unpacking the equipment The IBP-YAG has been carefully packed for shipment. If the container arrives damaged in any way, please contact the shipper. Inspect each item as it is unpacked, looking for dents, scratches or other damage. -
Page 11: Frame Grabber Setup
2.2.2.1 Cooling Water connection See Figures 1-2 and 2-1 The IBP-YAG requires a reliable source of cooling water for proper operation. This can be a re-circulating heat exchanger, chilled facilities cooling water, city water, etc. Connect the “Cooling Water In” fitting to the cooling water source. Connect the “cooling water out” to a return or a drain depending on your system. -
Page 12: Verify That The System Is Operating
Two setup files have been provided with each IBP-YAG measurement head. The setup files contain calibration information and are unique to each IBP-YAG head. The setup files are associated with the serial number of the IBP-YAG hardware in the form: ~YAG<Serial number>_CW.cfg or ~YAG<Serial number>_PULSED.cfg For the initial checkout, select the ‘CW’... - Page 13 alignment target on the shutter to center the beam. Note: The alignment beam can not be viewed by the instrument. • Take any safety measures necessary to avoid exposing personnel to the laser beam. Refer to section 1.5 for safety recommendations. •...

Page 14: Begin Data Collection
2.5 Begin data collection • If the program is not already running, start the LBA-PC software on the computer by Clicking on the Windows ‘Start’ button, then ‘Programs’, ‘Spiricon’, ‘LBA-PC’, and ‘run LBA-PC’. When the program starts, verify that the correct configuration file is being used… the name of the configuration file in the title bar should match the serial number of the IBP-YAG head. -

to the software manual for more information on the calculation and monitoring capabilities of the software. 2.6.2 Calibration Before attempting to take accurate measurements with the IBP-YAG, the instrument must be calibrated with no energy on the detector. The following steps will calibrate the sensor for maximum accuracy. -
Page 16: Chapter 3 Maintenance And Storage
Chapter 3 Maintenance and Storage 3.1 Storing and transporting the IBP-YAG If the IBP-YAG will be stored for an extended time, transported, or will be exposed to freezing temperatures, the cooling water must be drained to avoid damage. Disconnect the electrical and signal cables from the IBP-YAG. Disconnect the Cooling water lines and drain the water into a collection basin. - Page 17 Cleaning procedure: 1. Blow off the surface of the optic with an air bulb or photographic type canned air. Blow as close to parallel to the optic as possible to push the contaminates off the glass. This step should remove any large particles from the surface. If the surfaces are still contaminated, continue to step 2 Figure 3-1 2.

Page 18: Removing And Replacing The Sampling Optics
3.2.2 Removing and Replacing the sampling optics Replacement of the sampling optics involves partial disassembly of the IBP-YAG. The following procedure will allow access to the sampling optics for cleaning or replacement. Remove the Leveling Plate to allow access to the bottom of the instrument. The Leveling Plate may be removed by carefully prying down on the plate next to each of the leveling feet The studs of the leveling feet will pop out of the pads attached to the plate. - Page 19 Remove the indicated screws to release the front panel. Remove the thumbscrew and spacer from the shutter. Figure 3-3 Slide the front panel and shutter away from the instrument. The shutter is attached to the front panel with 2 springs. Do not let the shutter or springs touch the sampling mirror. Figure 3-4 The Mirrors may be removed by removing 3 screws and clamps.
- Page 20 replaced with the mirrored side UP. The mirrored side is not always easy to identify, it is indicated with an arrow mark on the edge of the mirror. Figure 3-5 Before reassembly make sure that all mechanical and optical surfaces are clean and free of dust. Reassemble the instrument by following the steps in reverse order.

Page 21: Appendix A Cooling Water Requirements
Appendix A Cooling Water Requirements The IBP-YAG needs a reliable flow of cooling water to dissipate the energy of the laser. The required cooling flow is dependant on the laser power level and the initial coolant temperature. Note: If the inlet cooling water is chilled to below the dew point, condensation will occur inside the unit. - Page 22 Cooling Water Outlet Temperature °C (°F) Initial Temperature: 27°C (80°F) Water Flow Power Input (kW) liter/min Gal/min 45.8 (114.4) 36.2 (97.2) 45.8 (114.4) 33.0 (91.5) 39.4 (102.9) 52.1 (125.8) 31.4 (88.6) 36.2 (97.2) 45.8 (114.4) 30.5 (86.9) 34.3 (93.7) 41.9 (107.5) 49.6 (121.2) 29.8 (85.7) 33.0 (91.5)
