Exp-1 BPW34 PIN Photodiode forward and reverse bias characteristics for fixed irradiation.
Exp-2 Dependence of photocurrent on light intensity.

  • Highly sensitive photo-diode.
  • Easy set-up.
  • Multipurpose power supply with digital display.
  • Dark current.
  • Photo-diode.
  • Photo current.
  • Forward bias.

The BPW34 is a high speed and high sensitive PIN photodiode in a miniature flat plastic package. Due to its water clear epoxy the device is sensitive to visible and infrared radiation. The large active area combined with a flat case gives a high sensitivity at a wide viewing angle.
In the present setup, the photo-diode characteristics in forward bias and reverses bias configuration for fixed irradiation is measured. Also, the dependency of photo-current on different irradiation will be measured.
