Sf has ucl?

[R@ndom]

I was playing with a sf bezel from a G2Zl and the reflection of my dome light was blue. My memory tells me vaguely that this means ucl lenses. Does it?

SureFire have used multi-layer anti-reflective coatings since they introduced it on the M3 'about a decade ago'. Sometimes the coatings are more obvious than others like how the variations in anodisation shades can be more obvious under certain lighting conditions...

It doesn't mean that the window is a UCL. SureFire used to use Pyrex, now they are using Borofloat - both with AR multi-coatings.
