This preserves camera from possible high illumination, but can lead to confusion, if you expect to see some image. The default shutter parameter is "closed". Afterwards, you can set them using :meth:`.t_amp_mode` and :meth:`.t_vsspeed`. To get the list of all possible parameter combinations, you can use :meth:`.AndorSDK2Camera.get_all_amp_modes` and :meth:`.AndorSDK2Camera.get_max_vsspeed`. Upon the connection, the parameter are typically set to the slowest mode. These parameters greatly affect the camera sensitivity and readout speed. Often cameras have a lot of different readout parameters: channel, amplifier, vertical and horizontal scan speed, etc. It is possible to pass these parameters on camera creation: cam = Andor.AndorSDK2Camera(temperature=-50, fan_mode="on") By default, the fan is turned off, and the cooling is set to the 20'th percentile of the whole range (e.g., -80C for Andor iXon).
When applicable, it is important to properly set the cooling setpoint and the fan mode. To get around it, the camera is put into a "default" state any time the connection is opened. Since the manufacturer DLLs do not provide methods to get most of the camera parameters (such as exposure or ROI), it is impossible to know them when connecting the camera. However, there's a couple of differences from the standard libraries worth highlighting: They support all the standard methods for dealing with ROI and exposure, starting and stopping acquisition, and operating the frame reading loop. The operation of these cameras is relatively standard.
Otherwise, DLL resources might become permanently blocked, and the only way to solve it would be to restart the PC. It is important to close all camera connections before finishing your script. To get the total number of cameras, you can run :func:`Andor.get_cameras_number_SDK2`: > from vices import Andor The cameras are identified by their index, starting from zero. If the DLLs are located elsewhere, the path can be specified using the library parameter devices/dlls/andor_sdk2: import pylablib as pll By default, library searches for DLLs in Andor Solis and Andor SDK folder in Program Files folder (or Program files (x86), if 32-bit version of Python is running), as well as in the folder containing the script. For 32-bit version, correspondingly, atmcd32d.dll or atmcd32d_legacy.dll. For 64-bit version it will be called atmcd64d.dll or atmcd64d_legacy.dll. The required DLL can have different names depending on the Solis version and SDK bitness.
The code is located in :mod:``, and the main camera class is :class:`2Camera`. It has been tested with Andor iXon and Andor Luca. This is an older SDK, which mainly involves older cameras.
In most cases, you have Andor Solis already installed to provide the drivers and to communicate with the cameras to begin with. The required DLLs are distributed with Andor Solis or the corresponding Andor SKD.
The manual describes the cameras and capabilities in more details. The newer SDK, called SDK3, covers newer cameras: Zyla, Neo, Apogee, Sona, Marana, and Balor. The details of this SDK are available in the manual. The older one, called SDK2, or simply SDK, provides interface for the older cameras: iXon, iKon, iStart, iDus, iVac, Luca, Newton. General camera communication concepts are described on the corresponding :ref:`page ` Andor camerasĪndor implements two completely separate interfaces for different cameras.
