The C-995 phase-locked-loop optical chopper incorporates Direct Digital Synthesis in order to provide rock-solid, crystal controlled accuracy and stability. Its chopping frequency can be controlled to a precision of .001 Hz and has effectively zero frequency drift. A large, five digit LED display indicates the internally set chopping frequency, or in the External Sync mode, the measured frequency of the external clock signal.

Provides chopping rates from 4 Hz to 5000 Hz without the need to change blades
The unit may be computer controlled via its bi-directional serial port
May be phase-locked to an external clock source
Enclosed blade for minimum windage and noise
Or exposed blade for maximum flexibility on a crowded optical bench
Operates from 95 to 260 VAC, 50-60 Hz

Standard accessories

Mounting rod and stand, Rs-232 cable, Power Cord, Operating Manual
