  • This field is for validation purposes and should be left unchanged.

The standard modulators 350, 360, 370, 380 and 390 series are built as intensity modulators with a polarizer aligned to the crystal axis. The same modulators can also be configured for use as polarization rotators, voltage variable wave plates or phase modulators. All of our modulators can be constructed with all the crystals inline such that the full cell is active as a phase modulator, but in this configuration it cannot be used as an intensity modulator, polarization rotator or variable wave plate. Once the modulator is built as a phase modulator it cannot be re-configured as an intensity modulator.
