詳細(xì)介紹

Model 651-1
Dual Aperture Light Chopper
The model 651-1 uses the standard head. This is a dual port design allowing two optical beams to be modulated simultaneously at different frequencies, f1 and f2. Two reference (sync) outputs are made available at the control unit, corresponding to f1 and f2, for use with signal recovery processing electronics, such as a lock-in amplifier.

Two small blanking plates are provided with the standard head and one of these allows either the top port or the bottom port to be blanked off to reduce the effect of any stray light passing through an unused path. The second plate provides some measure of beam restriction when using large diameter beams on the higher frequency (ａnd therefore smaller aperture) port. The standard head is supplied complete with a flat base plate to allow the unit to be used in a free standing mode on a bench type surface. A special feature of this support allows the head to be used in the horizontal plane for modulating vertical beams. The base plate can be removed and standard optical mounting supports employed instead if preferred.
