Continue measuring the ND filters. Finally, the calibration file is generated and saved to the disk
and is directly available in the spectral response module.
6. This button repeats the last measurement. Always check the resulting spectral distribution of the
filter and the center wavelength after each measurement for reliable results and repeat the last
measurement if it seems insufficient. This issue may happen, for example, when the
measurement head is not inserted entirely, and the measurement is started too early.
7. Clicking the Cancel button stops the whole calibration procedure and discards all previous
measurements, and the calibration procedure needs to be started again.
8. The following filter to be measured is displayed in the image.
Mount the calibration plate in front of the filters and tighten it with the screw cap.
Push the measuring head into the holes of the calibration plate as far as it will go.
