Does anyone know where I can find what the meanings are for all those letters manufacturers put on their objectives. I've seen the short list in the Olympus resource center, but I am finding that is just the tip of the iceberg. I would like to know about Olympus codes past and present.
Also, there seems a time when Olympus did not put the tube length on the objective barrel. I am assuming it was for infinity objectives, but I am not sure (I think my Vanox uses an infinity tube and none of its objectives has the tube length printed on them).
Doesn't anyone believe in making a standard AND sticking to it in microscope manufacturing?!?

Hello Will,
At the Nikon site there is a fairly comprehensive listing;
http://www.microscopyu.com/articles/opt ... specs.html
that covers all I can think of.
All the best,
Mike

Hi Will,
In addition to what Mike has suggested, you may wish to check the files in Olympus directory on Gordon Couger's science-info.org website:
http://www.science-info.org/micro/docs/olympus/
I found there a following excerpt:
"With D Plan objectives, field flatness is guaranteed up to F.N. 20. Ideal for photomicrographic purposes, they are widely used in research, educational and routine work."
For older Olympus optics try the brochures on the following page:
The Unofficial Olympus OM Sales Information File: Photomicrography
