section.
- Right mouse click anywhere inside a graphics window now opens a floating
options menu. This is easier than finding and clicking on the option
button to the left of each graphics window.

in the frame of a graphics window. Thus, it is no longer required to
search and find the specific update button, although the update button
is still available.

grating and hologram surfaces and to simplify entry of VLS parameters.
- Hikari glass catalogue updated.

existing basic aperture shapes (circular, elliptical, rectangular).
The polygons need NOT be convex and any shape is allowed. Up to 10
polygons may be defined on a surface and may be logically combined
with other basic aperture shapes. Each polygon may have up to 50 vertices.
- Ghost image analysis has been added. Since it is based on the built-in
inverse ray trace, it is not required to rebuild the optical system.
This allows immediate ghost analysis and a very fast way to identifying
the most disturbing surface combinations.
- Lens catalogs have been updated.
- Some tolerances in the ISO drawing dialog were not correctly initialized.
As a result, manually entered tolerances could not altered. Now corrected.
- Coordinates in the title bar of the lens layout window were incorrectly
displayed when the window did not have input focus.

used on calling macro files. Previously specification of the full
directory structure was required.

aberrations and diffraction effects.

of type LPT (LightPath) and to the very general URN (University of
Rochester) profile.

which allows a wider range of unusual pipes. Rays are checked for TIR (total internal
relection). Also hollow pipes are now supported.
- The "actions" tab in the preferences dialog was not correctly
initialized. This is now corrected.
|
Version 4.80

function.
- PSF gray scale plots can now also copied to the clipboard.
- Plot of phase change in multilayer coatings has been added.
- Plot of group delay dispersion added.
- Optimization targets/constraints can now conveniently selected from
a list box. This simplifies construction of the merit function.

from toolbar icons, which are associated to the lens layout windows. This gives
an animated impression on the movements of the zoomed components.
|
Version 4.67
(2.June 2002) |
- All graphics windows now allow multiple zoom operations by
dragging a rectangle successively over the desired plot area. In this way, even

(TIR) surfaces.
- The program is no longer consuming almost all of the processor load
when it is running idle.
- The autofocus option has been extended and now allows adjustment of the
field and wavelength parameter from other modules, e.g. when used
as compensator in tolerancing.
- In defining optimization constraints, operators like
=, >, < no longer must
be padded with blank characters. That is, constraints such as "efl=100"
(typed without blanks) are now correctly interpreted.

(04.July 2001) |
- Special apertures can now be edited in the spreadheet editor
similar to other surface data.
