Re: Zeiss 'Achrostigmat' 44 01 51

No idea. I know on the finite achrostigmat ones they had a cap that went on the end of the objective. It doesn't look like it is flush to the surface of the metal. Maybe that white ring holds a cap on?

Edit: Or maybe I'm thinking of an antiflex cap going on top?

I would think anything immersion would have a higher NA than 0.65.

Is there a picture?

Re: Halp identifying mechanical stage and leitz objective

The P on Leitz objectives mean they are for polarizing light microscopy.

Pictures of your stage would be helpful.

Jochen makes a good point. The early Standards, in which the RA was the first,have the Zeiss metal plate on the front of the base and do have the better 13 blade metal light port and iris. But, the only RAs I have seen, do not have the interchangeable objective turret. My RA, as you see the third fr...

Re: Microscope part help

The 18 has the changeable turret, the others except the WL, do not.

This will accept the 6V 15W in base lighting system.

Re: Microscope part help

Hobbyst66 is right. The telan lens allows the system to stay at 160mm TL and not to be adaptable to newer systems.

The 5X indicates the turret has holes for 5 objectives.

The Zeiss systems before the infinity Axio series were 160mm TL (Tube Length). The Telan lens is used to keep the optics at 160mm tube length.

Welcome Grahame.

The Wild M20s are some really nice microscopes. I have a few.

Being in New Zealand, you probably have access to the Oamaru diatomite? The Oamaru diatomite have some excellent fossil diatoms and radiolaria.

Re: Doing Diatoms a Different Way

Hi Kurt,

Not exactly. The amount of adhesive seems to be the key. But I find when I use small 'flat' diatoms, they will stay in place but when I use large 'thick' diatoms they tend to float around more. :(

You will also need a relay lens in the photo tube. Here is what mi...

The Gum Tragacanth should be a finely ground powder. You stir in small amounts of the Gum Tragacanth to the 30ml of water until it is syrupy. You can take it off the heat and then stirring in the glycerin and alcohol will make the adhesive very liquid and can be filtered after stirring in the glacia...

Re: Doing Diatoms a Different Way

The tip would vary in size depending on how it is pulled. Most of mine are less the half a micron, but if you get them too thin, they are too wispy for use. I do make some which are about 1 micron, to move large diatoms which have stuck to the slide during drying.
