Well... let's kick this new place off with some info.
It's the same as in this post; http://www.laserpointerforums.com/forums/YaBB.pl?num=1196266417 (just stripped down only containing optics)
Perhaps everyone could post their own bits of info on optics, so we'll have a sort of forum optics Wiki for people to refer to (or those that are unable to operate a search button
)
And we'll begin:
CONVERGING LENSES:
Thicker in the center than on the edges; they cause parallel light rays emanating from an object to converge onto the same point.
Plano-Convex Lens:
Lens with one flat side and one convex side (bulging outward).
Positive Meniscus:
Lens where the concave side (curving inward) is less pronounced than the convex side (bulging outward).
Biconvex Lens:
Lens with both faces bulging outward.
Convex Lens:
Lens with one side bulging outward; the greater the bulge, the more the light rays converge
DIVERGING LENSES:
Thicker on the edges than in the center; they cause parallel light rays emanating from an object to diverge.
Plano-Concave Lens:
Lens with one flat side and one concave side (curving inward).
Concave Lens:
Lens with one side curving inward; the greater the curvature, the more the light rays diverge.
Biconcave Lens:
Lens with both sides curving inward.
Negative Meniscus:
Lens where the concave side (curving inward) is more pronounced than the convex side (bulging outward).
ADDITIVE COLOUR MIXING:
SUBTRACTIVE COLOUR MIXING:
