Re: Identifying asbestos

I think I have found some samples identified as Blue Crocidolite and White Asbestos or Chrysotile
these images were produced using a Zeiss POL image crossed and Red compensator
and Darkfield

I was using a filter paper Disc taped to a Glass funnel amber latex hose to a battery operated blower

Re: LED vs. Halogen test

That's a cool Idea Very nice
I thought about doing that but no filter I could find was small enough to fit as there is not much room inside the head
the method of holding one of the polarizers between your eye and the eyepiece is pretty precarious esp if you want to take pictures

Re: Identifying asbestos

seems like the general consensus is quartz ,mica etc sliders are not as important as differing refraction oils
my question now becomes I did not know of anything other then the immersion oil I use for 63x and 100x objectives where do I obtain such a wide variance of oils
