Open the CIPO recordAbstract From the Canadian patent
A color synthesizing scanning electron microscope having a scanning primary beam of electrons directed toward a specimen (12), is configured to produce color images of high information content. The microscope comprises at least two wide energy bandwidth secondary electron detectors (14 16, 18), arranged around the specimen at predetermined variable angles for receiving, electron emission from the specimen subsequent to incidence of the scanning primary electron beam. The wide energy bandwidth secondary detectors detect electrons with trajectory or positional differences and convert the positional differences to signals for synthesizing color. The signals from the wide energy bandwidth …

Why it's free to use
- Filed July 22, 1992 and granted May 25, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 22, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 22, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
