Quick Answer
Opto Electronic Devices are physics and electronics practical apparatus built around light-sensitive and light-emitting components: photo cells, solar cells, LDRs, LEDs, photodiodes and phototransistors. They are used to plot V-I and light-intensity characteristics, study the inverse square law and find Planck's constant from the stopping potential, with a mercury vapour lamp and a photomultiplier tube as extra items. JLab currently lists 14 items in this category.

Frequently Asked Questions
How is Planck's constant found with the apparatus in this range?
The Planck's Constant Apparatus measures the stopping potential of a vacuum-type photo cell lit through a colour filter set from a lamp house on a double-rod optical bench, and gives Planck's constant, h, from it; a second version does the same with a mounted solar cell, a low-voltage DC supply, a voltmeter and a micro-ammeter.
What supplies and meters do the LDR, LED, photodiode and phototransistor apparatus have?
Each is a panel with the device mounted on it and two meters for voltage and current. The LDR and LED units have regulated 0-3 V DC supplies, the photodiode and phototransistor units 0-10 V DC at 50 mA, and the three-device kit 0-3 V DC at 150 mA.
