Photoconductive Cell (Noun)
Meaning
A transducer used to detect and measure light and other radiations.
Classification
Nouns denoting man-made objects.
Examples
- The photoconductive cell is used to measure the variations in light intensity that correspond to the patterns on the disk in a laser-based data storage system.
- A cadmium sulfide photoconductive cell is often used to measure low-intensity light, as it has high sensitivity and is relatively low-cost.
- A photoconductive cell consists of two metal electrodes separated by a thin gap of light-sensitive material such as selenium or cadmium sulfide.
- Photoconductive cells have been developed to operate over a wide range of electromagnetic spectrum, from visible light to infrared and ultraviolet radiation.
- A photoconductive cell is used in light meters, such as those found in cameras, to measure the intensity of incident light and adjust exposure settings.
