Well, I see Seiko is introducing a 1.74 index lens (Vision Monday, vol. 14, iss. 14; pg.40). The article mentioned the lens has an abbe value of 33.
This brings me to my latest question...
What property(ties) of a material determine abbe value? For that matter, what properties dictate the index of refraction? In other words, WHY does poly carbonate disperse light to a greater degree than allyl diglycol carbonate?
Thanks in advance for your answers. I always enjoy reading them because they introduce me to new areas of science (and I usually comprehend most of what you are saying). I'm just waiting for someone to ask a question about soteriology or transubstantiation so I can excersize my Theological synapses!
