Clip 1: What is Tolerancing...

This is a basic introduction to tolerancing as a subject - it summarises what is covered in the WinLens Tolerancer manual.

For the optical engineer there are five key questions that need to be answered when converting a paper design into a successful product.

  • What are the errors that can happen in the manufacture of this design
  • What are the performance effects of those errors individually
  • What limits [tolerances] do I need to place on those errors
  • What will happen when I make a batch of lenses to those tolerances
  • How can I get the glass shop and machine shop to follow those tolerances

We discuss these very briefly!


Clip 2: Tolerancer: an introduction...

WinLens Tolerancer is designed to help you create sensible tolerances for your lens system [the design must be rotationally symmetric]

This clip provides a very quick run thru of the tools available to help in tolerancing:

  • Standard graphs from WinLens
  • Define performance requirements
  • Sensivity analysis - tables of data - linked to the graphs
  • Tolerance editors - statistical feedback & many tools for tolerance assignment
  • Monte Carlo simulations of a batch of lenses made to current tolerances - linked to the graphs
  • ISO 10110 drawings - editor and flexible preview - highly customisable

Clip 3: ISO 10110 drawings II: drawing options on preview form...

In the preview form we show how:

  • to use the zoom/pan options
  • to adjust the location of the default symbols and dimensions
  • to add extra text & symbols to this drawing [or all drawings]
  • to see the extra drawing for aspheric surfaces, and how to edit them]

Clip 4: ISO 10110 drawings III: customisation...

In this clip we will show you how to customise the drawing logo, layout, language & font.

So far we have worked with the default drawing, and showed how you can edit the tolerances, adjust the symbols and dimensions, and add extra symbols & text.  These extra symbols & text can be setup so they apply to all drawings, so that is a good start to customisation - but we can do much more.
