Class Information
Number: 257/431
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Responsive to non-electrical signal (e.g., chemical, stress, light, or magnetic field sensors) > Electromagnetic or particle radiation > Light
Description: Subject matter wherein the non-electrical signal to which the device responds is electromagnetic energy in the light frequency/wavelength range (i.e., from infrared (except where the response is mainly due to thermal heating due to the infrared radiation) to visible and ultraviolet).
