Description of the MDF file format
The MDF file format is a simple ASCII-format which includes the main data of a beam measurement – the
spatial power density distribution. MDF stands for “mailable data format”.
By means of this standardized format conversion problems between different evaluation programs are sup-
posed to be reduced and a safe data transmission, e.g. per e-mail, is supposed to be ensured.
The files are arranged as follows:
1
st
line:
MDF 100 (file identifier)
2
nd
line:
Number of image points: in x-direction in y-direction
3
rd
line:
Size of the measurement range: length in x (mm) length in y (mm)
4
th
line:
Position along the beam axis: z-position (mm)
5
th
line:
Transversal position of the center of the measurement range: x-pos y-pos (mm)
6
th
line:
Amplification of the measuring signal: enhancement (dB)
7
th
line:
Number of averages: number
8
th
line:
Offset value displayed by the measuring device: offset-value
9
th
line:
Wavelength-value
10
th
line:
Power value
11
th
line:
Focal length value
12
th
line:
Date, time value
In the following lines the data can be found.
There is a maximum of 80 characters per line.
Comments
Comments are inserted as additional lines, into the lines after the file identifier.
The comment lines each start with a semicolon.
