Optomechanical Chopper OMC-1 is designed to modulate a continuous or semicontinuous optical radiation by blocking the radiation beam with an opaque metal wheel that has some slots in it.
OMC-1 consists of an optomechanical unit and a control unit. For ease of assembly, they are connected by a two-socket cable. Control unit also includes power supply.
The Chopper is equipped with a display panel and synchronization signal output (TTL, 0 – 5 V).
Key Characteristics ОМС-1
To achieve wider frequency range, the chopper is supplied with two wheels that have different number of different-shape slots. Within each of the two ranges, the modulation frequency is controlled by varying the wheel rotation speed.
