OpTaliX Version History

Version 11.00
Changes in version 11.00:

  • The interpolation of two-dimensional surface deformations (imported via INT files) has been significantly improved, in particular when the deformation contained very steep slopes.
  • A scaling problem in the "RAW2INT" command fixed. It was created by an inappropriate conversion of raw values to integer numbers in the INT file.
  • The program did not make use of multiple processors (if existent) but run in single processor mode instead. This effect was erroneously introduced. Now fixed.
  • The ray grid size (NRD = number of rays across diameter) can now increased to 2048 x 2048 rays to allow modelling of very fine structures in the entrance pupil.
  • The lens databease item [ABBE] now correctly accounts for dispersion offsets (DVO), if existent. Previously only the fixed abbe number of the catalogue glass was reported.
  • OHARA i-line glasses added to glass catalogue.
  • Minor changes.

Version 10.90
Changes in version 10.90:

  • Weight calculation did not account for mirror surfaces when ENVironment conditions (temperature and pressure) were activated. Now corrected.
  • ENVironment calculations did not correctly account for manually entered dn/dt data when automatic thermal coefficients from catalogue glass are unavailable.
  • The number of variables and functions in the LM optimization is now unlimited. Previously there was a limit of 100 variables and 20000 functions.
  • NHG glass catalogue updated: Internal transmission added, dispersion coefficients of IRG materials added.
  • Minor corrections on sagittal MTF when the fields are defined in the X/Z plane only.
  • Minor changes.

Version 10.80
Changes to version 10.80:

  • "Undo" and "redo" options added. A virtually unlimited number of parameter changes can be undone and redone.
  • Ray aimung, i.e. the generation of rays, is now significantly faster, is more stable and produces less spurious output.
  • A bug in the distortion calculation was corrected, when the field was defined by paraxial or real image height (YIM or YRI).
  • Minor tweaks.

Version 10.70
Changes to version 10.70:

  • The number of allowable sources for illumination analysis can now be changed by the MAXSRC command. Theoretically there is no upper limit (only limited by physical memory). Note: Without explicit specification of MAXSRC, the default number of allowable sources is 200.
  • The number of plot rays in illumination analysis changed randomly. Now corrected.
  • The wavelength used for illumination sources can now defined on the command line or in macros. Previously, only dialog based entry was possible.
  • Updated glass catalogue: CDGM
  • New glass catalogues: EP plastics from Mitsubishi Gas Chemical, and OKP plastics from Osaka Gas Chemical.
  • Updated glasses in special catalogue: IRG22, IRG24, IRG25, IRG26, IRG27, Zeonex350R, ZeonexF52R
  • Import of Synopsis optical design files (*.rle)
  • An inproper dispersion model of CDGM infrared materials was used. The index calculation is now correctly based on the Herzberger equation.
  • When the field definition is changed in the configuration dialog, the numerical field values are now automatically converted according to the new field definition.
  • When attaching an optical coating to a lens surface in the surface editor, the refractive indices of the coating substrate and the lens are now automatically checked if they are equal within a predefined index tolerance.
  • The commands ADX, ADY (aperture decenters) and ARO (aperture rotation) are now recognized again. They were inadvertently deactivated.
  • Minor tweaks.

Version 10.60
Changes to version 10.60:

  • Distortion function DISY corrected when the field definition was set to YRI (real image height).

  • The following analyses now also support field definitions in the X-direction:

    • MTF vs. field,
    • field aberrations,
    • distortion,
    • astigmatism,
    • relative irradiation.

    Previously, the fields were required to be defined along the Y-direction to create meaningful plots.

  • Vignetting (relative irradiance, RIRR) now correctly takes transmission effects (POL Y) into account. Previously the normalization to the reference field was omitted for this condition.

  • Illumination analysis: The number of rays used for plotting is now stable. Previously, plot rays could be "lost" under special conditions.

  • OpTaliX version 10.60 will be the last version to support 32-bit and 64-bit operating systems simultaneously. All future editions of OpTaliX will support 64-bit systems only.

  • Minor tweaks.

Version 10.50
Changes to version 10.50:

  • Index of refraction plot for selected glasses added.
  • Code V import and export: Support of pickup surfaces and central aperture obscurations.
  • Macro editor: The lens data items [ss], [so] and [si] were not recognized and returned error messages.
  • The tolerance sensitivities TSX, TSY, TSZ, TSA, TSB, TSG returned incorrect results due to an internal parameter shift. Now corrected.
  • TMAT command fixed where the transformation matrix is referred to global coordinates.
  • Wavefront plot vs. wavelength corrected. Previously the wavefront at only four wavelength were drawn even if more wavelength are defined.
  • SUMITA glass catalogue updated.
  • Minor tweaks.

Version 10.40
Changes to version 10.40:

  • The zoom command 'ZOO ...' was erroneously, temporarily deactivated and did not update the zoom editor. Now corrected.
  • Global surface coordinates (GSC command) corrected for systems that utilize combined tilts (alpha + beta + gamma).
  • The colour of graphics windows can now be inverted (dark background, white text). Adjustable in the Preferences section, colour tab.
  • Distortion plot corrected when the field definition was set to YRI (real image height) or YIM (paraxial image height).
  • Minor tweaks.

Version 10.25
Changes to version 10.25:

  • The reference manual is now opened in the application which is associated with this type of document (PDF). This way, the manual is opened in any PDF-viewer as defined by the file association of this extension (PDF). Previously, the Acrobat Reader was mandatory.
  • The UDS/SPS editor was erroneously invoked when editing asphere coefficients of an anamorphotic surface. These coefficients can be edited in the surface editor and need not the extra dialog. This behaviour was merely annoying and did not affect data integrity.
  • The following glass catalogues were updated: CDGM, NHG, HIKARI, NIKON, APEL
  • Astgmatic focal shift (ASF): Generation of object rays improved.
  • Ray generation on very wide angle systems (e.g. fisheye systems) improved in terms of accuracy and speed.
  • Zemax import/export: Improved support of coordinate break surfaces, Q-type surfaces, square and elliptical apertures and aperture offsets.
  • Minor tweaks.

Version 10.1
Changes to version 10.1:

  • New commands available: PSDX and PSDY calculate the PSF-diameter in X- or Y-direction at a defined intensity level. PSE calculates the ellipticity from the PSDX/PSDY ratio.
  • Creation of private (melt) glasses caused the program to crash under Win-10 operating systems only, older Windows versions (XP, Vista, 7) are not affected.
  • The following window handling problems specific to the LT-version have been eliminated:
    - Field aberration and astigmatism plots are now updated on window resize.
    - The menue items "Seidel aberration plot" and "Seidel aberration numerical output" activated.
  • Export to Code V: Aperture offsets ADX, ADY, ARO and Q-Type surfaces (QBF, QCON) are now converted.
  • Beam Propagation: Numerical stability of field amplitude calculation significantly improved.
  • DLF tolerance on aspheric surfaces calcuated incorrect functions. Now corrected.
  • Minor tweaks.
