PHOTO TRANSISTOR, PHOTO DIODE, LIGHT DEPENDENT RESISTOR (LDR), etc, are sensitive to light. Each exhibits a finite characteristic for incidence light. Wavelength and intensity of incidence light determines the output characteristic of the above devices. This trainer consists of one each of the above transducers. A common incandescent light source with variable intensity illumination is provided with this trainer. A separate output terminal for each transducer is provided for measurement. A plot between the intensity (for three different light intensities) and the output voltage is recorded. The trainer has built-in power supply. Specifications: - Opto devices: LDR, photo diode, photo transistor- 1 each.
- Source: A variable light intensity source.
- Built-in power supply.
