The Microscope classes¶

Several classes with a more pythonic interface exists. All these classes implement the same methods as described by the BaseMicroscope. Currently the following implementations exists:

Local Microscope via the Microscope class.
Dummy Microscope via the NullMicroscope class.
Remove Microscope via the RemoteMicroscope class.

The BaseMicroscope class¶

class temscript.BaseMicroscope¶

Abstract base class for microscope classes.

Do not use BaseMicroscope directly, instead instantiate one of the subclasses, like Microscope or RemoteMicroscope. The Subclasses implement all the abstract methods.

abstract acquire(*args)¶: Acquire images for all detectors given as argument. The images are returned in an dict indexed by detector name.

abstract get_beam_blanked()¶

Return whether the beam is blanked.

Return type: bool

The accuracy of this value depends on the accuracy of the calibration within the microscope.

On FEI microscopes this corresponds to the state of “User Beam Shift” (in different units though).

abstract get_beam_tilt()¶

Return beam tilt as (x, y) tuple.

The units this is returned in are radians. The accuracy of ths value depends on the accuracy of the calibration within the microscope and thus is better not to be trusted blindly.

Parameters: shift (Tuple[float, float]) – Shift value

set_beam_tilt(tilt)¶

Set beam tilt to position tilt, which should be an (x, y) tuple, as returned for instance by get_beam_tilt().

On FEI microscopes, this will turn on dark field mode, unless (0, 0) is set. If (0, 0) is set, dark field mode is turned off.

set_camera_param(name, param, ignore_errors=False)¶

Set parameters for camera name. The parameters should be given as a dictionary. Allowed keys are described in the get_camera_param() method.

Raises: KeyError – If an unknown camera name is used.

New in version 2.0.

Note

On Titan 1.1 software setting the “binning” property also changes the exposure time.
On Titan 1.1 software images acquired after setting the “exposure_time(s)” property might not be acquired with the new setting, even though this property reflects the new value when read.

Also see Restrictions.
