Thank you so much JW. I thought as much but it is good to get a second opinion.

Best

I have an original manual for the Universal epi-illuminator which came with my Labophot 2.
I can scan this for you if it's of any use.

I'd love to.........but how? It's 10 pages and each page scans as a jpeg, and each jpeg is over the 300kb limit.

Thanks for taking the time to scan this. Guess I should of read you posting better. This isn't what I was looking for.

What is the chance that you can take the 'cover plate' off that rotating polarizer so I can see how it works mechanically and then photograph the entire slider? I'd like to machine one since they rarely come up for sale on eBay. That's the only thing I am missing other than 2 filters.

Speaking of filters, I have the L900C, IF, NCB10 and ND16. What are the other 2 in you picture?

Hi
It was quite expensive so I rather not pick it apart as long as it works.

The labels of my filters are:
GIF
ND2
ND16
NCB 10
NCB 14 (two of the same)

As the polarizer/analyzer is quite expensive, and it is probably not so difficult to make your own polarizer and analyzer it may be a good idea to try to make your own. I suggest that you have a fixed polarizer attached to the plastic filter marked ND 32 that you already have. Then you can have a "loose" polarizing filter in the "dust-tight slider" - gravity will keep a "loose" polarising filter in plase and it will be quite easy to take it out and rotate the filter.

Regards Jörgen

Thanks, no problem if you are not comfortable removing the cover plate, I totally understand. Thanks for listing the filters too. I have the analyzer slider and the full wave red plate compensator, just missing the rotating polarizer. I made a spacer for the thinner full wave plate to take up the slop since I don't have the rotating polarizer. I ended up placing a 1 3/8" polarizer disk in the illuminator slot and rotating it by hand.

You want to try something fun, you should try putting back the aperture blades in a condenser or fixing the the ones that are in the illuminator. Once you know how it really isn't that big of a deal.

Actually - It was fixing some loose illuminator aperture blades that made me more careful than curious. The effect will probably last a few month

Nice picture!
