Nikon microscope parts for sale on ebay

I hope this is ok to post this note on here - if not, admins can remove.

Hi Paul, Are you using your flash in TTL mode or manual? You only need a tiny amount of flash power close up and that looks like a fairly powerful flash, and TTL doesn't work very well close up as the flash sensor has to read the reflected light and may not be in a good position to do that.

Hi, Assuming this is the lens you have (I found it on eBay so it may be the very one) there is one little clue that you didn't mention in your post, and that is the apostrophe after the second H like this H' http://www.photomacrography.net/forum/userpix/2664__57_2.jpg On a typical ray diagram the le...

Hi, A macro set up is good for 1x to 5x but beyond that you will need to use a microscope objective on your camera. Read this excellent FAQ which explains your options.

So whilst others may know a lot more than me about DIC, I can share what I have learned so far. Firstly the polarising filters need to crossed at 90 degrees to ach...

Exhibition prints (Image added)

The exhibition was titled "Art of Type" and had work from a number of artists on the theme of type, fonts, words and letters. My exhibit was a collection of letters from objects I had around the house,...

Thanks for the info Pau. I have to confess I'm a complete novice when it comes to insects. The little blobs aren't water so I will try cleaning in alcohol and see what it looks like then.

what was the magnification and NA of the objective used? The objective is a Nikon CFI 5x na 0.13 BD using the darkfield cube on a Nikon Epiphot 200, Nikon PL 2.5x and ISO 200. I think the LED illuminator is 3w, as the controller says 3w max. Did you use any polarizers on the brightfield image? No, ...
