The invention relates to a method and device for calibrating a measuring instrument with at least two partial systems (<I>K;M</I>) which can be , displaced with regard to one another and with means for generating an image of at least one first partial system (<I>K</I>) on at least one detecting component (<I>A</I>) of at least one partial system. The invention provides that after establishing a mathematical model a parameter set, which , quantifies influencing factors on systematic measurement errors of the measuring instrument and which has at least one parameter is derived from the , mathematical model. Afterwards the imaging of the structure elements (<I>S</I>) of a first partial …

Why it's free to use
- Filed March 27, 2002 and granted May 1, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 27, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
