Electronic flash project
Posted: Thu Jul 12, 2018 2:10 pm
Like most microscopists I have had 'electronic flash' on my wish list ever since I realized that blur and cilia were synonyms without one.
After a false start with some prisms, bought without a clear idea as to how I was going to utilize them and which therefore are still in a drawer, I decided that getting hold of a 'dual head cube' (beam splitter) was a more practical potential solution.
The idea is to attach the cube directly to the lamp-house connecting tube, which would give two 90 degree ports.
The cube has Telan lenses, as it is designed to take finite 160 binocular heads.
This means that in order to be able to attach the lamp-houses I need to place a spacer under the dovetail in order to clear the protruding Telan lens.
To do this I need longer versions of the original screws. Unfortunately I don’t know the screw designation.
I read that with the screw diameter and the number of threads per cm it is possible to identify it.
If anyone knows what it is or can calculate it via the photos below I would appreciate it.
Images:
1) Found one on ebay. As can be seen the cube was missing the dovetail and the tightening screw sleeve. As I had these spares, I crossed my fingers hoping there would be no unpleasant surprises and put in an offer.
2) Cube with dovetail and tightening screw sleeve added.
3) Lamphouse as it should be attached.
4) Cube in place.
5) Simulated position of the lamphouses.
6) screws (diameter is 2mm)
7) screws + dovetail
Happy to report that both the cube and the Siedentopf binocular head were in excellent condition.
Have placed the Siedentopf on my microscope and given my Jentzsch a vacation. It was due some R & R and a very thorough clean.
