he information below is from handouts distributed to
attendees of the January 1999 Photonics West conference and the May Laser FX 99
conference. The instruction
manual for the Model 6210 (Revision 0, February 10, 1999) also has the same
specifications as the Photonics West handout, with two exceptions noted below. At the Laser FX 99 conference, Cambridge representatives stressed that these are preliminary specifications and are subject to change. For example, at Laser FX 99 the representatives stated that the Small Angle Step Response Time had been halved to 0.15ms. As of this writing (June 10 1999) these are the most recent available specifications. Please check with Cambridge for any updated information. |
