Changing Lenses

Does anyone have an instructional document on how to change lenses? I have a Tesio300 that came with a 2X lens installed and a 0.5X lens as an extra and I want to use the 0.5X lens but can't. I thought I had it in correctly by removing the ring light and screwing it in underneath but when I tried to calibrate it to the ROI solid block master I could not get the .562 square to fit in the graphics display window. Any help would be appreciated.Slight smile

  • Hi James,

    You will need to ensure you've defined a seperate Probe with this mag size, so that the calibration software knows which lens size it is (and thus which of the rectangles to instruct you to measure that will fit in the Field Of View).

    For example, you should already have a probe built up for your 2x lens using the following components

    TESA_VISIO300_ZOOM\TESA_VISIO300_ZOOM_2x

    You will need to create a new probe for you 0.5x lens by going into Probe Utilities and building a probe with the following components :-

    TESA_VISIO300_ZOOM\TESA_VISIO300_ZOOM_0.5x

    Select this new probe before calibrating.

    Incidentally, it's strange that you have an ROI slide on a TESA machine. Normally, the TESA machines should be shipped with the Hexagon Metrology glass calibration slide. This will become more important in future versions (V4.1, V4.2) as additional calibrations are being added that require this generic slide.
