set(new_position, *, timeout: float = None, moved_cb=None, wait: bool = False)

Set lens position, returning immediately if already there.

class id4_common.devices.crl_device.PyCRLSignal

Bases: ophyd.EpicsSignal

EpicsSignal with a value sub-component and EGU readback.

class id4_common.devices.crl_device.BeamsizeSignal

Bases: ophyd.Device

Beamsize handle in microns.

The underlying focalSize setpoint and fSize_actual readback PVs are in meters and do not fully converge, so this device writes to the setpoint (microns -> meters) and reports the readback (meters -> microns) without enforcing a match: mov crl.beamsize 10 writes 10 um to the setpoint and returns immediately. The raw meter-valued PVs remain available as crl.beamsize.setpoint and crl.beamsize.readback.

setpoint

readback

set(value, **kwargs)

Move the setpoint to value (microns); finish immediately.

get(**kwargs)

Return the readback in microns.

property position

Readback in microns.

read()

Report the readback as a single microns-valued field.

describe()

Describe the microns-valued field reported by read().

property hints

Hint the microns-valued field for plotting.

class id4_common.devices.crl_device.PyCRL(*args, **kwargs)

Bases: ophyd.Device

PyCRL compound refractive lens controller.

set(value, **kwargs)

class id4_common.devices.crl_device.EnergySignal

Bases: ophyd.Signal

Signal that moves the crl to a new energy.

abstractmethod put(*args, **kwargs)

Raise NotImplementedError — use set() instead.

set(value, **kwargs)

Move crl to the specified energy.

class id4_common.devices.crl_device.ZMotor

Bases: ophyd.EpicsMotor

EpicsMotor that optionally tracks X/Y when Z moves.

set(new_position, **kwargs)

Move Z and optionally track X/Y.

stop(*, success=False)

Stop Z and optionally X/Y.

id4_common.devices.crl_device.make_crl_class(motors_ioc=DEFAULT_MOTORS_IOC)

Return a CRLClass with lens motors bound to motors_ioc.

Parameters:

motors_ioc (str) – IOC prefix for the crl stage motors, e.g. "4idgSoft:".
