Re: [meteorite-list] Which Polarized filters for TS ?
HI I have bought two sheet of polarized filter A4 dimension, it works very well!! http://www.3dlens.com/polarizer.htm Ciao Francesco Moser - Original Message - From: PolandMET [EMAIL PROTECTED] To: meteorite-list@meteoritecentral.com Sent: Friday, September 21, 2007 3:33 PM Subject: [meteorite-list] Which Polarized filters for TS ? Hi What polarized filters You use in Your microskopes. I use normal, cheap two Polarized (PL) filters for digital cameras. But I dont see strong, deep colors like on photos from proffesional microskopes. On some thin sections I see good contrast, but on others there is low contrast or even near no colors :) So the secret is to use any special or better (read more expensive) polarized filters ?

Great idea, Francesco! And, great prices, too. (fifth one down is A4 priced) http://www.3dlens.com/shop/polarizer.php http://www.3dlens.com/shop/polarizer.php Now I can try Tom Phillips' suggestion: http://www.meteorite.com/meteorite-gallery/Micro_Visions.htm http://www.meteorite.com/meteorite-gallery/Micro_Visions.htm Did you try the other sheets to determin the A4 as best?

You can use this bulb in your picture when you look at a meteorite (slice) in reflected light. In that case the light is directed onto the - usually flat - surface of your meteorite sample. But, when studying or photographing thin sections, you examine your samples in transmitted or in cross-polarized light. In that case, the light passes up through your thin section from below - that's where your (sub-) stage glass is broken in the photo of your microscope. This rectangular opening one can see right under the broken glass plate, ... that's where the light must come from when you look at a TS in transmitted or in polarized light.
