Classes

EMBLSlitBox(*args)

User can define sizes of horizontal and verstical slits by entering direct size and pressing Enter or by using up and down buttons. Slits operations are enabled accordingly to the detected focusing mode. - Collimated beam (both enabled) - Horizontally focused (hor. disabled and ver. enabled) - Vertically focused (hor. enabled and ver. disabled) - Double focused (both disabled) User can stop slit movement by pressing stop button (enabled if slits moves).

class mxcubecore.HardwareObjects.EMBL.EMBLSlitBox.EMBLSlitBox(*args)

Bases: AbstractSlits

User can define sizes of horizontal and verstical slits by entering direct size and pressing Enter or by using up and down buttons. Slits operations are enabled accordingly to the detected focusing mode.

• Collimated beam (both enabled)

• Horizontally focused (hor. disabled and ver. enabled)

• Vertically focused (hor. enabled and ver. disabled)

• Double focused (both disabled)

User can stop slit movement by pressing stop button (enabled if slits moves).
