Product description

The VARIABLE FREQUENCY shutter/chopper Model EOP-CH-50, EOP-CH-60, and EOP-CH-61 consists of a blade (vane) mounted on a motor with a limited rotation angle. The position of the blade follows the direction of the current in the motor winding. Current in one direction will set the shutter to the open position and current in the other direction will set the shutter to the closed position. Alternating the current will cause the blades to open and close the chopper at a frequency range from DC to 12 Hz for the EOP-CH-50, or DC to 50 Hz for the EOP-CH-60 and EOP-CH-61. This method of chopping is jitter free. High reliability and long life is achieved by eliminating the use of a brush type motor or gear heads. 

When used with our EOP-DCH-50 or EOP-DCH-60 driver and an external clock input, a frequency stability of 0.005% is possible. This ultra high stability cannot be achieved with a rotating chopper. The chopping operation is locked in phase to the clock input; no additional circuitry is needed for phase locking. The driver also enables the user to set the shutter in either a closed or an open position when it is not running. 


Configurations:
Models EOP-CH-50, EOP-CH-60 and EOP-CH-61 come with a mounting plate that allows horizontal and vertical mounting.
Models EOP-CH-50-B, EOP-CH-60-B and EOP-CH-61-B are boxed with a window for laser light and can be mounted horizontally and vertically. 


The shutter/chopper is especially suitable for low cost dedicated applications, OEM, built into an instrument/system, and for portable systems
