Re: Outfitting a Lab Bench for DIC "Economically"

Thanks for responding Kevin.

Any idea where on line the documentation exists for the older Type I
and Type II Zeiss DIC equipment.....I would like to compare them.

I have seen the delamination problem in a small number of Zeiss
objectives I have seen. Without knowing their history, it is difficult
to say why they suffered delamination.

I seem to remember the older Zeiss DIC was supposed to be used with
Plan Achromats, correct? If so, which ones were recommended?

Any guess as to what a Type II Zeiss DIC transmitted light setup for an
Universal frame is worth?

Thanks

Thanks for responding Kevin...it is really appreciated.

Could you give me a brief history of what was available for Zeiss in
terms of DIC and when?

Any links to a discussion for implementing DIC..Zeiss or otherwise?

Type II DIC? Is there a Type I DIC? How does one tell the difference?

Assuming I invest in DIC for one of the Zeiss Universal frames I have
available, where would you go looking for it?

In assessing an used DIC setup, what should one look for? I seem to
recall that Zeiss has a reputation for delamination in their optics.

If one decides to move to a different frame/manufacturer, who would you
recommend and why? I ask because I am trying to decide whether
investing in DIC would be a good reason to move to infinity optics with
their newer and hopefully better optical designs.

Finally, can a person use a DIC system from one manufacturer on an
other manfacturer's frame such as an Olympus DIC on a Zeiss frame?

Thanks

The Type I system was superceded by the Type II in the mid '70's. The type
I system uses one prism above the objective. This type of system can work
quite well with a limited number of objectives, Olympus uses it to great
effect.

The Zeiss type II system has its problems. I just spent hours rebuilding
plastic prisms lubricated with a grease that turns into glue. The customer
got billed for my effort but it frustrated the heck out of me. It is more
vesatile.

By the way, I've never seen a delaminated Zeiss objective. In fact I've
seen about 2 dead Zeiss objectives, their stuff is well made. However the
Zeiss attitude is enough to drive me crazy and I'm half German. Geez, if I
was a hundred percent German I couldn't stand myself.

If you want a modern 'scope and Nomarski at a reasonable price Olympus is a
great vendor. On this coast Olympus has dealers and extremely good sales
people.

As to using one companies Nomarski and anothers microscope, anything is
possible. However it doesn't work in general and there would be so many
problems.... Keep my name in mind if you want to do that, it would take
about 6 months. Lets see, $80 and hour for 6 months... I'd be rich! At
least I could drink the better class of beer.

I am considering outfitting my lab bench with transmitted DIC
capability.

I would like to do it as economically and efficiently as possible.

I have a number of Zeiss Standard/Universal/PhotoMic stands available
that are already outfitted for brightfield, darkfield and phase.

I would guess the question that comes to mind is it better to outfit
these excellent but older Zeiss 160mm stands with DIC capability or go
with a different stand (and perhaps a different manufacturer) which
would likely be with newer infinity optics?

If it were your money, how would you spend it?

Thanks

I'd be tempted by the Type II Nomarski that Zeiss made. This requires a
Nomarski ring for each objective but add it to a Universal and it is just
to
cool!! It can be adapted to Plan Apos, Plan Flourites and Plan Achros,
getting the right prisms may take some time but the results are worth it.

Since you don't use it all that frequently it would work well. Infinity
correction right now is valuable if your in the business, 160 works fine.
