OpTaliX Version History

Obsolete Versions 4.xx

Versions 6.xx
Versions 5.xx
Version 4.98
(9.March. 2003)
  • Corning Quantum-Focus lens catalogue added.
  • Corrected raytrace intersection error for non-sequential aspherical surfaces.
Version 4.97
(5.March. 2003)
  • Test plate lists from Neeb-Optik, DD-Optik and Befort added.
  • The power series terms on aspheric surfaces has been increased to 10^18 order. Previously it was limited to 10^10 order.
  • MTF values are now defined in the range from 0.0 to 1.0. Previously, MTF ranged between 0.0 and 100.0 (in %).
  • The command line is immediately activated by keyboard activity, unless a dialog box is active. Recognized characters are letters a-z, A-Z, numbers 0-9 and the blank (space) character. Thus way it is no longer required to use the mouse to select the command line prior to entering data.
  • Dn/dT data and expansion coefficients of catalogue glasses can now be overridden by manually entered data.
  • EXM command has been added to define linear expansion of front surface mirrors.
Version 4.96
(24.Feb. 2003)
  • The font size in the text output and command output windows is now adjustable via the preferences section.
  • The background of graphics windows is now selectable via the preferences 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.
  • Graphics windows may now be updated by simply double-clicking anywhere 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.
  • A variable linear spacing (VLS) grating option was added to supplement grating and hologram surfaces and to simplify entry of VLS parameters.
  • Hikari glass catalogue updated.
  • Transverse aberration and OPD fans can now displayed horizontally or vertically. This is user selectable in the preferences section.
Version 4.93
(4.Feb. 2003)
  • Infrared glasses IG2 to IG6 from Vitron added to special catalogue.
  • The PMI attribute (mirrored side walls on light pipes) now also works for cirular cross sections.
  • Grid distortion plot now also works correctly with zoom systems.
  • A bug with tilted GRIN surfaces was inadvertently reintroduced. This is now corrected.
Version 4.90
(19.Jan. 2003)
  • Polygon aperture elements can now be defined in addition to the 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.
  • The path to macro files as defined in the preferences is now correctly used on calling macro files. Previously specification of the full directory structure was required.
  • In optimization and macros, incorrect values for surface decenter (XDE,YDE,ZDE) and tilts (ADE,BDE,CDE) were returned. This is fixed now.
Version 4.86
(24.Nov. 2002)
  • Extended object imaging, based on Fourier methods. Takes into account aberrations and diffraction effects.
  • User defined dispersion can now be assigned to Gradient index media of type LPT (LightPath) and to the very general URN (University of Rochester) profile.
  • Rectangular light pipes can now be "sheared", 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
(05.Oct. 2002)
  • Two-dimensional surface deformations can now be applied to all surfaces. Such deformations are typically obtained from interferometric measurements and let you analyze the as-built performance of your optical systems.
  • Two-dimensional surface deformations can now be applied to all surfaces. Such deformations are typically obtained from interferometric measurements and let you analyze the as-built performance of your optical systems. Supports Code V INT-files and Orbscan topography format.
  • Catalogue lenses from CVI-Laser added.
  • Path information for storing macros and user defined graphics can now be defined in the preferences section.
  • Surface sag calculation added.
  • Logarithmic scaling of thin film transmission/reflection plots was not always correctly recognized. This is now corrected.
  • Gray scale PSF over field diagonal did produce a blank output image at rare circumstances. Now corrected.
  • Fixed incorrect order of tilts/decenter after surface insertion/deletion.
  • Fixed update problem in surface editor when changing global references. Previously, decenter and tilts were not correctly updated even though the system was in right condition.

  • Element drawing according to the ISO 10110 standard has been added.
  • Coatings designs can now imported from "The Essential Macleod" thin film design package.

  • 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.

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 very small details can be enlarged.
  • The X- and Y-coordinates of the cursor are displayed in the title bar of the lens layout plots and are permanently updated.

  • The syntax range of the thin-film formula editor has been extended. It allows now arbitrary factors for multilayer groups such as HL, HLH, LHL, etc. For example 1.83(HL)^6 is correctly interpreted. Some minor tweaks also increased the robustness of the coating editor.
  • Gradient index materials from Grintech, Jena have been added.
  • Longitudinal aberration plot for on-axis and off-axis field points has been added.
  • The scaling tool has been extended to scale a lens by specifying the required focal length (EFL), overall length (OAL), system length (SYL), object-image distance (OOS) or entrance pupil diameter (EPD).

  • 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.
  • The complete Arthur Cox lens design library has been added (Pro-version only).
Version 4.64

Slider bars have been added to the perspective view. They allow change of the viewing perspective in almost "real time" (depending on computer speed and model complexity).
Version 4.33
(22.July 2001)
