Watch your secondary obstruction size. Bigger = less contrast.

>>there is Fluorite and there is CaF2 but they are not the same chemically at all>>

Just to inform you, CaF2 and Fluorite are one and the same. CaF2 is Calcium Fluorite, or Fluorite for short.

Ok, the latest word in writing.

Posted By Roland Christen
Fluorite is fluorite (CaF2), a crystaline material.

The rest are glasses. None are Fluorite. Some are made from Fluorite material with other stuff added, some have no fluorite in them, but none of them are crystaline.
