ALV/CGS-3 Compact Goniometer System
The ALV / CGS-3 compact goniometer is a self-contained system with 22 mW HeNe laser, ALV-proprietary optical fiber based detector, APD-based single photon detector, ALV/LSE-5003 electronics and ALV-5000/EPP correlator. It offers identical overall performance for simultaneous measurement of DLS & SLS data and the optical detection was designed such that a significantly higher count rate per mW is obtained. The complete shielding of the unit ensures it is a class 1 laser product. The goniometer angular range is from 17° to 150° with a resolution of 0.025° and a travel speed of 20°/s.
