The Model 6210 is the smallest fast (ILDA 30K and above) light show scanner available.
T

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.
