Open the CIPO recordAbstract From the Canadian patent
A scanning confocal microscope (50) capable of providing ultraviolet (UV) excitation. The optical train substantially corrects scanning and focusing errors over the wavelength range that includes UV and visible wavelengths. In a particular embodiment, the lenses (27, 30') in the common path portion of the optical train are corrected for chromatically induced scanning errors while extra lenses (60, 65) are provided in the forward UV path to correct for focusing errors due to longitudinal chromatic (visible/UV) aberration.

Why it's free to use
- Filed April 8, 1992 and granted March 26, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 8, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 8, 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.
