Sep 2013Terahertz Technologies Inc.Request Info
The C-995 phase-locked loop optical chopper provides crystal-controlled chopping rates of 4 Hz to 5 KHz using only one blade. The use of direct digital synthesis permits the rate to be set to a precision of 0.001 Hz and provides quartz-crystal stability. Frequency settings may be made via front-panel controls or its bidirectional RS-232 port, or the device may be phase-locked to a user-supplied external clock. Both enclosed and open-style chopper heads are available.
