Synopsis Surface and Material Properties - guidelines for when to use one or both Solution "The answer to whether or not you need both a Material and a Surface Property is ""sometimes"". There are some effects that occur at an interface that is best modeled as a Surface Property:
Question I have a zoom system where I want a certain surface parameter to be zoomed in all configurations. However, in some configurations, I want the variables to be tied together (equivalent to each other), and in others I want them to vary independently. How do I do this? Synopsis Tying...

Question I have a lens system that will be altered when subjected to the environment where it will be used. This environment will cause thermal and mechanical stress resulting in lens surfaces deforming to asymmetric surface shapes and glass materials changing refractive index as a function of...
Question I am working on an optical model where I want the system to be telecentric in both object and image space. How do I do this? Synopsis Controlling a lens system to be telecentric Solution When a system is telecentric in both object and image space, it is called "doubly telecentric". OSLO...
Question Several times I have had the need to measure a distance, say from the front surface of a lens to the aperture stop, or the length of a group of lens elements (for example, surface 5 to surface 11). Is there an easier way of doing this than manually adding up all the thicknesses? What...
Where the feature tutorials each cover a single capability, these application tutorials walk through complete, realistic design problems end to end: the workflows optical engineers actually run. Each includes the tutorial PDF plus the models and property files to follow along.
