Sonora Medical Systems, Longmont, Colo, has released its latest product, a handheld endoscope-testing device—the Firefly—which measures the luminous radiation of standard medical endoscopic light sources, fiber optic cables, and endoscopes.

The company‘s device consists of an integrating sphere, a light meter, and various adapters used to interface with endoscopic equipment used in surgical applications.

The Firefly’s one-button operation provides the user with an objective and repeatable measure of the light output, expressed in lumens, from each of the components in the endoscopy chain. The data can be used for presurgical luminosity confirmation, predictive maintenance, product acceptance and ongoing endoscopy quality assurance programs.
