Re: Making Permanent Microscope Slides of Insects
photomicro mentioned the compilation of Ernie Ives articles by the Postal Microscopical Society. The two volumes have been available for some time, I purchased my copies a year ago, and in fact the print run may have sold out by now. The books cover preparation of many kinds of specimens, but a larg...

Thanks for this microcosmos.

And yes, it's particularly nice to see microscope...

I think you are correct apochronaut, the engraving does look decidedly Vickerish, and the objectives look familiar. I think I have seen them listed specifically as Vickers infinity objectives, or perhaps mounted on a Vickers 'scope. I seem to remember being told that Vickers did start sourcing objec...

Re: Vickers Microplan 4 objective puzzle - how to solve it?
I read that history and remain puzzled regarding the lengths, since I have a set of Vickers/Cooke-Baker objectives, all Microplans and despite the name difference, one could easily view them as a matched set. The Cooke-Baker 10X .25 is not spring loaded and measures 42mm from thread base to tip. Th...

Re: Vickers Microplan 4 objective puzzle - how to solve it?
Hi MicroBob Vickers and their subsidiaries have used a variety of parfocality lengths: 24mm, 34mm, 44mm and, after their change to DIN specification 45mm. My guess is that your 4x Microplan is 44mm; pretty close to DIN spec. Tube length is 160mm. Location of the intermediate image was 10mm down the ...

Thank you for making these videos available AntoniScott. You can read descriptions of how to do this, or have someone tell you, or see some photographs, but there's nothing like watching someone doing it in real time. Very much appreciated.

Re: Huge list of stains available to me, any suggestions?
Well, others will almost certainly expand greatly on this list, but Toluidine blue O, for many uses; Safranin O and fast green FCF for plant sections; Alcian blue likewise; haematoxylin and eosin (I assume bluish?) for animal tissue.
What a treasure trove that list is!

Hi petew The DIN standard for objectives specifies not only the mechanical tube length (160mm), but also the parfocal distance of the objective, i.e. the intended distance from the objective mounting flange to the object, which for a DIN standard objective is 45mm. So your longer objectives appear t...
