DEVICES AND METHODS FOR MEASURING LIGHT

摘要

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.

主权项

1. A device comprising:
a) a light diffusing element comprising:
i) an element comprising a top portion, a bottom portion, and a side portion, wherein said top portion comprises a screen, said bottom portion comprises an inner surface that is substantially hemispherical, and said side portion comprises an inner surface that is substantially cylindrical, and wherein said side portion is connected to said top portion and said bottom portion; andii) an outlet port in said side portion, wherein said outlet port is substantially parallel to said top portion and is adjacent to said bottom portion, and wherein said outlet port is configured to receive a light conducting conduit.
