Principle
1. Used for the particle nature of light experiment to explore the phenomenon of photoelectric effect.
2. Experiment circuit diagram printed on the panel of the experimenter, easy for students to understand the experiment. Built-in voltage and micro-current sensors, no collector, can be directly connected to the terminal, in the proprietary software template, can realize the continuous recording of data and in the form of numerical values, images and other forms and real-time presentation on Windows, Android, iOS system terminals, solving the problem of difficult to measure the photocurrent in the traditional experiments, facilitating the demonstration, and greatly enhancing the efficiency of the classroom.
3. Built-in voltage divider circuit, the voltage can be adjusted through the knob to explore the phenomenon that the photocurrent increases with the voltage and reaches the saturation current.
4. Built-in dimmer, through the knob can adjust the size of the light intensity, to explore the larger the light intensity, the larger the saturation current phenomenon.
5. Equipped with 3 kinds of color filters, positioning slot design, easy to install, you can explore the relationship between photocurrent and voltage under different frequencies of light irradiation.
6. Built-in power direction adjustment device, can be adjusted according to the experiment of the positive and negative direction of the voltage, to explore the curb voltage.
7. The panel comes with voltage, micro-current digital display module, can be used independently, can also be used in conjunction with a computer to complete the experiment.
8. Aluminum alloy photocell cover design, effectively avoiding the influence of other stray light, small experimental error.
9. Supporting special experimental software, preset templates, in the form of curves to automatically record data changes, the results of the experiment is more intuitive and obvious.
Experiment
Used to investigate the photoelectric effect, verify saturation photocurrent, curb voltage and other experiments
Maintenance
1. The device should be placed in a cardboard box if not in use. Use a damp cloth to wipe out the dust on the surface lightly. Avoid scratches caused by sharp articles on the surface
2. It is better to place desiccant in the cardboard box.
