Re: Optiphot nose piece question
I was most interested in this post, as I have an Optiphot 1 and a Labophot 2. The former has a nosepiece like the one illustrated, with no extra lens, and having the objectives facing towards the user. However, the Labophot 2 nosepiece has them facing away, which as Pete says, is much more convenien...

Re: ND filter vs filter for phase contrast
The ND filters are merely to reduce the light intensity. Whilst it might seem that this is possible just using the rheostat to reduce brightness, for photomicrography, the bulb is run at a certain voltage/current to attain a suitable (known) colour temperature. This was more important for film than ...

Re: nice microscope c.1900 but with puzzling objective type
Sounds to me as if it is an anastigmat lens, designed for photography, hence the iris. More modern (but still 1970s onwards) equivalents are the Zeiss Luminar and Leitz Photar range. They form a real image, without an eyepiece and give magnification ranges from x1 to x 20 isn, depending on focal len...

It looks to me as if the condenser fitted is the ELWD NA 0.3 type, which was the standard one usually supplied from what I can gather. It has only phase inserts, namely Ph L, Ph1, Ph2 and Ph3, with no bright-field setting as such. To set up the lamp and the field diaphragm, you use the Ph L setting,...

I assume you realise there is another part that is required to attach to your microscope? Unless you have a VANOX that is.
There were different adapters, such as the PM-ADG-3, PM-ADP and PM-ADF that fit to your microscope and then the Adapter L fits to.

Re: First microscope
The Alphaphot seems expensive for what was a student stand, and no trino head.
The Labophot is better, but only has x40 and x100 lenses.
(not an Optiphot BTW)
I would keep looking.
