Abstract: The invention provides a system and related equipment for the precise measurement of the output characteristic of a light source, e.g., a dental light curing unit (LCU) or light for photodynamic therapy, using a light collector, a light detector, and a computer programmed to deliver the value of the output characteristic of the light source to the user. The systems allow for the determination of a proper 5 exposure time or the selection of a light source as needed for a specific application. The invention also provides a light device.

Abstract: The invention features devices and methods for collecting and measuring light from external light sources. In general, the devices of the invention feature a light diffusing element, e.g., as a component of a light collector, connected by a light conducting conduit, e.g., a fiber optic cable, to a light measuring device, e.g., a spectrometer. This light diffusing element allows, e.g., for substantially uniform light diffusion across its surface and thus accurate measurements, while permitting the total footprint of the device to remain relatively small and portable. This light diffusing element also allows flexibility in scaling of the device to permit use in a wide range of applications.

Abstract: A system and method for real-time measurement of curing energy delivered to a simulated dental restoration from a source of curing energy. The system comprises a detector and a display. The detector measures at a location within the simulated dental restoration the amount of curing energy delivered by the curing energy source. The display displays the measured amount of curing energy in real-time. The system also comprises a temperature detector to measure temperature changes in the oral tissues during curing (teeth and gums). The system also comprises a video camera to record the operator's curing technique.
