Photoelectric Effect Apparatus (h/e)

FEATURE

  • Wide-range voltage power supply design

  • Filter and aperture integrated

  • CE Certification

 

DETAILS

Wide-range voltage power supply design

All of the power supplies have 110/220 input voltage switch, suitable for most of countries.

 

Filter and aperture integrated

The filters and the apertures are built into the front of the photodiode case, making it easy to keep clean and eliminating the need for a separate storage box. To change the aperture size in order to investigate the affection of different light intensities, simply pull outward on the aperture ring and rotate it to a different aperture. The filter wheel rotates independently of the aperture ring to select different frequencies of light. The wheel clicks into place, assuring that the filter is aligned with the aperture.

 

 

   Typical Experiments And Data   

1.  Calculate the Planck’s constant h through measuring the stop voltage of the photoelectric tube under different wavelenths of light. The relative error of result is less than 5%.

2. Research the V-I characteristic of photoelectric tube through selecting different filters or diaphragm.
