autopew.io.laser.chromium

Import and export functions for the Chromium Laser Ablation Navigation Software.

autopew.io.laser.chromium.get_scandata(scandict)[source]

Process a dictionary of scan information into a DataFrame.

Parameters:scandict (dict) – Dictionary of scan data.
Returns:
Return type:pandas.DataFrame

ScanData

autopew.io.laser.chromium.read_lasefile(filepath, encoding='cp1252')[source]

Read a .lase formatted file into a dictonary (one item per scan), and return this in the form of a DataFrame.

Parameters:
  • filepath (str, pathlib.Path) – Path to the .lase file to import.
  • encoding (str) – File encoding of the .lase file.
Returns:
Return type:

DataFrame

Notes

.lase files have all spot information as well as gas flows and all control options of laser operation. These are configuration files structured by blocks demarkated with square brackets, along the lines of:

[Scans]
Header=Scan Type,Description, ...
Scan0=Spot,"Spot 1", ...
[<other control blocks>]
...

Some of the values in this table are string-encoded tuples (e.g. “57950.00,37530.00,20734.50”) and dictionaries (e.g. “Dosage=1;DwellTime=1.00;LineSpacing=100.00;Laser.Output=10.00;…”).

autopew.io.laser.chromium.read_scancsv(filepath, encoding='cp1252')[source]

Read a .scancsv into a dictonary (one item per scan), and return this in the form of a DataFrame.

Parameters:
  • filepath (str, pathlib.Path) – Path to the .scancsv file to import.
  • encoding (str) – File encoding of the .scancsv file.
Returns:
Return type:

DataFrame

Notes

.scancsv files only contain spot information and do not edit the laser and gas conditions. These are essentially comma-separated values files, with a structure along the lines of:

Scan Type,Description, ...
Spot,"Spot 1", ...

Some of the values in this table are string-encoded tuples (e.g. “57950.00,37530.00,20734.50”) and dictionaries (e.g. “Dosage=1;DwellTime=1.00;LineSpacing=100.00;Laser.Output=10.00;…”).
