Re: 40x SPlan woes

Dirt or sand is not really a good sample to test. The layer beyond the cover glass is most likely already too thick for getting good quality image. For DIC why not just use the epithel cells from your mouth? Just grab some stuff with your fingers from the mouth insides and smear it on the objects ca...

Zosterodasys transversus

I would like to present a ciliate, I assume this is Zosterodasys transversa (Kahl, 1928) Foissner et al., 1994. I was first confused and thought this ciliate is Trithigmostoma cucullulus , Both ciliates have a comparable body shape, have a distinctive mouth funnel and impress by numerous eaten diato...

Thank you for the feeback.

75RR: yes samples taken from freshwater, a de-watering channel. Not too much interesting stuff, but more than I first expected.

Re: 23.2 vs 30mm

Speaking of FOV I replaced my Leitz 1x objective turret with the 0.8x, combined with the Fluotar objectives and the 30MM 10x/26 eyepieces, the FOV is incredible. There is a point where it is probably overkill as I find my eyes wandering around-LOL. Some may find this interesting in context of the F...

Re: Olympus BX60F

Hi Zero,
the adaption of a DSLR to your BX60F can be done rather cheap: just a tube without any optics:
viewtopic.php?f=24&t=5930&start=60#p73297.
The intermediate image of the microscope fits the size of DSLR with APS-C sensor size.

And does it need to be adjusted each time the turret is changed?
BX: If you change the objective you need to turn the condensor wheel on step further for the correct match of the DIC prism in the condensor. Since the condensor wheel-turret turns easily and smootly, I have not an issue with that.

Re: Does anybody know this vintage Zeiss?

Hi,
like Bob stated, delamination damage for the PlanApo 100/1,3 is extremely common. Difficult to argue on later price discounts for complete sets that are sold as not tested. And without any light source you cannot even blame the seller, since the microscope was not in working condition.
