Re: Darkfield Microscopy... is it that easy?

Yes, it really is that easy. Just put a dark-ground stop in the filter tray of the condenser, with the condenser iris diaphragm wide open. You will need to experiment to find the best size stop for each objective. Too small and direct light will spoil the effect. Too big and not enough light will ge...

World Microscope Day – 13th April

You have probably never heard of World Microscope Day, because this is its first year. It is intended to help promote microscopy, and the date commemorates the first use of the word “microscope” on 13th April 1625. You can find out more on the website and the Facebook Group: https://www.worldmicrosc...

Here is a UK source:

I have bought some of these before, and they were good, but it was several years ago.

Re: Bought an Olympus BH-2 and a Nikon SC; I have some questions..

Javier Have you tried to use the MCA photo eyepiece as a normal eyepiece? If it is anything like the Olympus NFK photo eyepieces, then it should function as a normal eyepiece, although you will probably need to get your eye very close to it. If it does not work as a normal eyepiece, then I suspect t...

Javier I have lots of documents for the Olympus BH-2: http://www.alanwood.net/olympus/downloads.html There is a set of exploded parts diagrams for the LB objectives, which might help to fix the spring on your 100, and there are instructions too: http://www.alanwood.net/downloads/olympus-lb-objective...

Re: Trinocular Microscope Tube

You mentioned changing your Canon EOS 500D.

That is a good camera for photomicrography. It works very well with the free EOS Utility software, which lets you control everything from your computer screen.

Re: Trinocular Microscope Tube

Owen We are making good progress. What you need now is one the adapters that were common for 35mm SLRs. They are usually in 2 parts. The lower part clamps to a 25mm tube and an eyepiece fits inside it. The upper part provides a few inches of extension and has a T-mount on top. You will need a T-moun...

Re: Trinocular Microscope Tube

That is an unusual adapter.

Let's start with the vertical tube on the trinocular head.

1) Is the outside diameter 25mm?

2) Can you put one of the viewing eyepieces in it? If you can, is the image parfocal with the other eyepiece?

Re: Trinocular Microscope Tube

Owen Please can you post a photograph of the trinocular head and the camera adapter(s)? And tell us which camera you are using? C-mount cameras have only a short distance from the front of the camera to the sensor. Canon EOS digital SLRs have a much longer distance, so an EOS digital SLR will not no...
