Settings for geological thin sections

For scanning geological thin section slides, it is necessary to adjust the camera parameters accordingly.

A) Optimize image quality settings

00. Press "F12" key or click the gears button to display the advanced settings window.

01. Activate "In-Camera Color Processing" on the "Image Acquisition" tab

02. Disable "Shading compensation enabled by default"

03. Increase the maximum exposure time limit from 500-1500µs (note: a higher exposure time might introduce motion blur in the scans)

04. Save the settings and restart the software

B) Adjust scan settings for a thin section

01. Place a thin section on the microscope that has empty regions that are still covered by a coverslip

02. Move to an empty region for automatic image adjustment and click the automatic image adjustment button

03. Move to the thin section for adjusting the gamma value to optimize the image contrast. Adjust the brightness accordingly.

04. Save these presets for Brightfield Scanning.

05. Now add the polarizer and analyzer in a plain polarized setting

06. Only adjust brightness and gain if necessary to make the image as bright as before. Use the Advanced Settings if necessary. Save this again as a new preset for Plain Polarized Imaging.

07. Rotate the polarizer into a cross polarized configuration

08. Adjust the brightness and gain again (use the Advanced Settings if necessary) and save it as a preset for Cross Polarized Imaging.
