Re: Salt mix

Filters are temporary, just for testing, will make something better :) ... Rotatable pol insert fits Nikon EPI illuminators, Microphots etc ( https://www.ebay.com/itm/323232270818 , 27mmx5.6mm) . It contains gears, when you are rotating one end, another rotates also. http://www.photomacrography.net/...

Sorry, No ... It is something I would avoid on principle. I suppose if you have a very heavy microscope and a very small fan the effects might be undetectable ... But is it worth the risk ? MichaelG.

Hello Saul,
there is a Leitz brochure 'Fluorescence Microscopy - Instruments, Methods, Applications' which includes the data for the barrier filters you are asking for.
I found mine as PDF in the web.
Any chance for the direct link ? Or document itself ?
Thanks !
