1.2 2008-06-17 * Great emprovement of the TeX and Postscript code. * New macros \newOptexpDipole, \newOptexpDipoleNolabel and \newOptexpTripole which allow very convenient definition of new components. * Enhancement of the lens design. Now much more types of lenses with two different curvatures and thick lenses are possible. The new parameters lensradiusleft, lensradiusright and lens are introduced. Unfortunately complete backward compatibility for the case where the lens is defined using only lenswidth and lensheight was not possible. Using the old behaviour is possible only by setting lenstype explicitly which in turn does not allow you to use the new features. * Added curved mirrors (new parameter mirrorradius). * Added binary gratings (new parameter optgridtype). 1.1 2007-09-06 * Considerably enhanced labeling of the components. Added new parameter 'labelref' which specifies the reference coordinate system for the label positioning and the rotation of the label. Default is labelref=relgrav, the label point is rotated together with the component, but the label text itself is not rotated. * parameter labelrelative is now obsolete, and replaced by labelref=relative. It will be removed in future versions. * parameter polwidth, bswidth, iwidth and owidth are now obsolete, and replaced by polsize, bssize, innerheight and outerheight for consistency reasons. They will be removed in future versions. * macro \polarisation was changed to \polarization for consistency. The old notation is obsolete and will be removed in future versions. * fixed bug: filling of all components with 'fillstyle' is now possible. * added some liftpen=1 in the code to fix the look of the lenses and the optgrid. 1.0 2007-07-18 first CTAN version
