DEFINITION

Classification: 313/110

(under the class definition) Devices which have an optical device structurally combined with the device so that the optical device and the lamp or discharge device constitutes a single integral device and devices under the class definition which are provided with an envelope which is designed to be especially transparent to particular wave lengths of radiant energy.

(1) Note. Optical devices as defined in the subclass definition include lenses, polarizers, reflectors, light diffusers, light valves, light obscuring means or any other means designed to alter the transmission of light rays in any manner.

(2) Note. See the class definition for the classification of lamps and discharge devices which are combined with a separable casing, jacket, shield, or envelope protective means. See the class definition for the classification of lamps and discharge devices which are combined with a separable optical device. See the class definition for the classification of envelopes, per se, for lamps and discharge devices.
