Laser test on WO triplet

Well, I did a laser test with a red laser on the WO Megrez 80mm APO (Fluorite?) Triplet and I am posting a picture (modified from original post) of what I saw. The strange part is that the photo that was posted that showed an middle Fluorite lens showed the middle lens as transparent and the front and rear lenses as green. But in my test the front and rear lenses are transparent and the middle lens shows red.
Is this because I used a red laser, or is it showing that the front and rear lenses are Fluorite and the middle lens is some other glass?

This was the original image of the laser test with the middle Fluorite lens.

Floyd do you have a link that talks about this laser test, or can you explain how it works? Never heard of it before.
