Aspirin is a common over the counter medication which is used to treat headaches and for a range of other medical conditions. When viewed by polarized light microscopy it takes on a whole new appearance, fairly incredible if I do say so myself!
How it was done:
The melting point of Aspirin acid is fairly low, because of this lower temperature a small amount was placed on a concave microscope slide and passed through a bunsen burner flame in a fume cupboard until it had melted. The slide was progressively passed through the flame being careful not to either burn the Aspirin, or break the slide. Once the material had melted it was left to cool and re-solidify.
The image was then captured using my normal polarized microscopy setup, which included;
- Nikon D5300 DSLR
- Radical RXL-4T Microscope
- Geology polarizing retrofit
- Trinamic stepper motor controller and stepper motor
- Helicon remote & focus
- Adobe Lightroom CC
Because the depth of field is relatively small, some images did require focus stacking which is where Helicon Remote & Focus came into the picture (pardon the pun).
