Re: Nikon Optiphot replacement bulb

You’ll need a vertical facing filament to fill the aperture at high numerical apertures. That's good to know. Thank you. My current Optiphot has a horizontal filament so it will be interesting to compare the two bulb varieties under various conditions. The bulb stated in the Optiphot manual is a Ph...

A nice talking point Michael.

As has been mentioned above, the great advantage of this technology is ...

It is a 40 page offering entitled 'Basics of the optical Microscope'. A.jpg Perhaps they no longer con...

Re: Eyepiece micrometer diameter?

They certainly made them in this size (21mm), I find in my box of micrometers that I have three of this size;

One a grid (10 x 10, labelled 1-10 down one side, A-J down the other)

One with 0-100 divisions

One with two such lines at right-angles, ie. a cross.

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 ...

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 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,...
