Re: Fluorescent capability?
Hi Everyone. I have an opportunity to get a fluorescent illumination capable microscope in a good condition at a reasonable price. I am considering adding it to my collection because it is different but also to experiment with a new lighting technique. I have seen a few images posted on this forum ...

Re: Fluorescent capability?
Rudi, This threads shows you how well 1-2 $40 UV LED torches work at low magnification. Relatively long exposure (~30 second or more) is needed though. Edit: here is the page: http://www.photomacrography.net/forum/viewtopic.php?t=33123&start=0 That thread also contains a link Pau's LED epi illumina...

Re: Fluorescent capability?
chlorophyll, some crustaceans and some minerals can produce fluorescence. I am not pursuing it because application is limited to me and cost is quite high, if you want the short exposure/low noise image at high magnification. At low magnification with long exposure, a powerful UV LED will work for ...

Re: Fluorescent capability?
Hi Rudi, At one time I was interested it obtaining a fluorescent microscope.. After doing some extra research, I decided against it.. It seems the high pressure bulb for lighting is a very expensive(to me)replacement item.. It has a life span rated in hours, not days... Along with the cost of the s...

Re: Pine needle cross section
Looks nice. Is this "double blading technique" two blades with a piece double-sided sticky tape between them? Any other tips or tricks? It is a slight variation, I use half a blade between the 2 cutting blades, it gives me thinner sections than the tape option. I have no real tricks other than to c...

Re: Pine needle cross section
Very nice colors! Like it very much. Hard to believe it is hand cut. Thanks! The secret is to make MANY cuts and select the best. Using the double blade technique I find it best not to cut at the end of the specimen but at least 2mm further in, gives better stability and more consistent results. Th...

I am still playing with sections stained using food dyes. This hand-cut CS of a pine needle was stained with red and blue food colorant. To try and get some color differences I have raised the PH of the blue and lowered it on the red, staining first with the blue and then the red. The sections are n...
