Description:

This instrument can carry on the experiment about the rule of photoelectric effect, and calculated Planck's constant according to Einstein's equation of photoelectric effect. Satisfying the students' grouping experiments, the instrument has features such as compact structure, fastness, convenient operating, steady performance, cheap and convenient service etc.. The anode of phototube is not shined directly, so the reverse current is small.

Details:

1. Color Filter: 635nm, 570nm, 540nm, 500nm, 460nm;

2. Sensititive Component: vacuum phototube;

3. Dark-current: ≤0.003μA;

4. Light Source: 12V/30W halogen tungsten lamp;

5. Length of Guide: 395mm;

6. Precision of Accelerate Voltage: ≤2%;

7. Measuring Error: less than ±15% compared with the recognized value (h=6.62619*I034 J.S).
