Acetylsalicylic acid (asprin) in cross-polarized light

Post by spongepuppy »

While I try to work out how to best capture images of actual critters under the microscope, I'm playing around with crystals in cross-polarized light with an improvised setup on my Leica ATC 2000.

I used isopropanol to dissolve the asprin before depositing drops of the saturated solution on standard microscope slides to dry, so chances are these are contaminated with other compounds.

It's interesting to see the different types of formations that arise - it's certainly a productive source of abstract images in nothing else :)

The following images were taken using a Marumi DHG +5 (200mm) achromat using some $5 ebay linear polarizing filters, a Nikon CFI BE 10x objective and a Nikon D7000.

Matt,

Vary nice images ! The second one (this almost B&W) is my favourite.

Have you tried other kind of alcohols for dissolving similar substances ?

@Marek: not yet - I've got some amino acids coming that are soluble in acetone, so we'll see. Using volatile solvents in the kitchen is not currently encouraged by other family members :twisted:

@Rogelio: thank you for your kind words :)
