    Optical Analysis by Darryl Meister

    Sometime ago, I started converting an old Excel tool of mine -- "OpticsLite," still available through OptiBoard -- into a Visual Basic application. During a recent vacation, I managed to finish the first "module" on ray tracing and lens analysis. (Details of the actual ray tracing sequence can be found in Jalie's Principles of Ophthalmic Lenses.) I am making this initial module available now, since it may be awhile before I have enough spare time to finish the next one. Note that this is only a beta version.

    Just a few usage notes:
    1) Move the red reference line to determine the off-axis performance at a given point.
    2) You can manually input variables by clicking the "Input" button.
    3) If the surface curves are too steep for a given blank size, the blank diameter is reduced in size automatically in order to compensate for this.
    4) The graph shows the tangential (red) and sagittal (green) power errors.

    What sort of problems are you having? (And keep in mind that these are Windows-based.) Also, I have zipped the program (in order to keep virus protection software from panicking.) You can download a free version of WinZip, if you don't already have it (though everyone really should), at WinZip.com.

    These VB programs require certain DLL files (bits of code shared by Windows programs to do common tasks) to run properly. Newer Microsoft operating systems (2000, XP, etc.) already come with all of the DLL files that this particular program uses, so I haven't created a full-blown installation package for it -- which would automatically install any missing DLL files. So if you can actually open and run the program, but get some sort of error about missing files, I can look at creating an installation package for you.

    How many times can we thank you for such an impressive tool.

    Just today, used it to show my optician how we are going to design some wrap sunglasses for Ms. Picky.

    Nobel Prize in Opticianry for you.

    Darryl,

    Everytime I fire up this software I can't help but to wonder if you have thought about making it compatible with external plugins to allow other programmers to expand on it's usefulness? I would love to add a few modules to it.
    1st* HTML5 Tracer Software
    1st Mac Compatible Tracer Software
    1st Linux Compatible Tracer Software

    *Dave at OptiVision has a web based tracer integration package that's awesome.

    Unfortunately, I have a lot of other stuff on my to-do list for the foreseeable future... But what did you have in mind?

    Best regards,
