Lighthouse Imaging Secures Patent

Photonics Spectra
Jan 2012
Lighthouse Imaging Corp. of Portland, Maine, has announced that a key element of its Endolume endoscopic testing device has been issued Patent No. 8040496 by the US Patent and Trademark Office. The patent is for the company’s Optical Bridge, which enables the Endolume to measure endoscopic light sources without a light cable. This allows for more accurate measurements. The Endolume handheld device measures the luminous intensity of endoscopic system light sources as well as light transmission through cables and rigid or flexible endoscopes. It enables clinical engineering staff to quickly troubleshoot the illumination for endoscopic systems before patient procedures.



GLOSSARY
luminous intensity
Luminous flux emitted by a source in a given range of directions; the unit of measure is the lumen/steradian, now known as the candela.
