Rotifer Testudinella patina in motion. Dark field and Pol.

Hi,

The rotifer Testudinella patina in motion.
Using darkfield and polarized light many interesting details are visible.
Between crossed polars (0:51) and with lambda retarder (1:15) its muscles are contrasted surprisingly good. :-)

Here the video:

Thank you Jens for the beautiful video.
Did you try oblique light on the same subject (how well did that work)? I am guessing oblique light + gradient darkfield background may be even better at capturing inner structures?

Hi,

you are absolutely right, more about that when my videos and/or photos are good enough...
The sample is still good for some more Testudinellae after two weeks. :-)

Jens,

Nice video! You track specimen movement very smoothly.

Are you using an automated stage with a joystick?

Indeed, that tracking was impossibly fast and smooth. My hands on my Nikon Labophot 2 cannot get close to that.

Hi Tom,

Hi Jens,

Ah ha! I hadn't thought about a gliding stage. Great idea. It looks like you have a lot of practice, too. You get very nice results!
