Hi,
had to give it a try after reading the PlasDIC post.
No idea about the origin of the Prism i've used, had it around for a while.
Just some tape for the slit to begin.
Tried on a Zeiss Jena Jenamed scope.
First impressions, slit approx. 3.5 mm, 50x objective.
Open aperture:
Slit aperture:
SlitDIC:
Slit Interference Contrast

For comparison, Nomarski DIC
Re: Slit Interference Contrast
Hi,
that looks very promising!
Is your setup similar to the PZO DIC with slit condenser? PZO uses a stit aperture in the condenser and an analyser in an intermediate tube between microscope head and observation tube.
Did you see a dependency on the orientation of the diatoms?

Hi Bob,
the basic design has to be the same as with PZO, but my prism height is fixed.
I didn't focus on details like specimen orientation or perfect rendering yet.
And diatoms are not my favorite specimens for real DIC.
But they look quite nice with slitDIC and i thought they are well suited for a quick comparison and reproducible views.
Using slit aperture and polarizer on their own already greatly improve the contrast of the image.
No news..
Printing an adjustable slit now.
