Is there a library (or something similar) available for optics including e.g. convex and concave lenses?
I fount this but it seems that this is not available as an official library …

You need the version 0.3.0 of the circuitikz package to draw thermistors. Once you have installed it, use the following code:
\documentclass{article}
\usepackage[europeanresistors]{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (0,0) to[thR] (2,0);
\end{circuitikz}
\end{document}
as you can see in the manual at page 10.
One simple possibility, using \draw and some of the predefined nodes:
\documentclass{article}
\usepackage{tkz-tab}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}
\tkzTabInit[lgt=2,espcl=1]{
$x$ /1,
$\sin(x)$ /1
}%
{
$-\pi$, $0$ , $\pi$
}%
\tkzTabLine{ , , t , , }
\draw[cyan,shorten >= 7pt,shorten <= 7pt]
( $(T11)!0.2!(T12)$ ) to[out=-50,in=230,looseness=1.4] ( $(N21)!0.2!(N22)$ );
\draw[cyan,yscale=-1,shorten >= 7pt,shorten <= 7pt]
( $(N22)!0.1!(N21)$ ) to[out=-50,in=230,looseness=1.4] ( $(T22)!0.1!(T21)$ );
\end{tikzpicture}
\end{document}

There is an extensive library in pstricks - maybe it helps. http://www.ctan.org/tex-archive/graphics/pstricks/contrib/pst-optic
