Pockels Cell on Stem

The Pockels Cell on Stem is a transverse Pockels cell for demonstrating linear electro-optic effect, and measuring half-wave voltage of a lithium niobate crystal. The pockels cell features an accurate, free-moving and smooth angle adjustment for demonstrating double refraction, in conjunction with a polarisation filter used as an analyser. 

The Pockels cell is mounted on a stem, making it compatible with an Optical Rider D for use on the Optical Precision Bench D.

Uses of the Pockels Cell on Stem

The Pockels cell is suitable for a range of experiment topics, such as:

• Pockels effect (linear electro-optic effect)
• Photorefractive crystal with no inversion centre
• Occurrence and modification of double refraction in external electric fields
• Half-wave voltage
• Modulation of refractive index
