Three types of Tunable Waveplates:
On this page you will find information about the following three types of tunable waveplates:
- Tunable Quarter-Wave & Half-Wave Phase Retardation Plates
- Tunable Dual-Wavelength Zero-Order Phase Retardation Plates: DUAL-WAVE
- Variable Phase Retardation Zero-Order Plates: MULTIPHASE
Tunable Quarter-Wave & Half-Wave Phase Retardation Plates
Tunable Quarter-Wave & Half-Wave Phase Retardation Plates [Detailed Datasheet, PDF]
A novel type of phase retardation plates (wave plates) representing a breakthrough in light polarization measurement and control is now commercially available.
The UVIR type plate can be adjusted to a quarter or half wave phase retardation for an arbitrary wavelength from 150 nm (vacuum-UV) to 6000 nm (far infrared) and the FIR type from 1 µm to 21 µm. Thus, the new plates replace tens of ordinary phase retardation plates required to cover these ultrawide spectral ranges. This is an exclusive feature and has no commercial counterpart. A combination of two optically contacted thin plates cut at a proper angle with respect to the optical axis forms a true zero-order phase retardation plate, similar in design to the Savart plate.
The required phase retardation is achieved by tilting the plate by 3° - 30°. This design is aimed at avoiding light reflection back to the laser system which in many cases results in complications.
The new phase retardation plates are indispensable in research with widely tunable or broadband laser sources like dye lasers, optical parametric generators and femtosecond lasers.
Although they have new and exclusive features and have no commercial counterpart, the tunable waveplates are offered at very competitive prices.

Tunable Dual-Wavelength Zero-Order Phase Retardation Plates: DUAL-WAVE
Tunable Dual-Wavelength Zero-Order Phase Retardation Plates: DUAL-WAVE [Detailed Datasheet, PDF]
The Tunable Dual-Wavelength Zero-Order Phase Retardation Plates feature true zero-order at both fundamental and second harmonic, broad bandwidth (typ. 50 nm) as well as phase retardation lambda/2 at the fundamental and lambda at the second harmonic respectively. Wavelength regions are 150 - 6000 nm (UVIR type) and 0.8 - 21 µm (FIR type).

Variable Phase Retardation Zero-Order Plates: MULTIPHASE
Variable Phase Retardation Zero-Order Plates: MULTIPHASE [Detailed Datasheet, PDF]
A modification of our tunable phase retardation plate allows continuous variation of the phase retardation in the range 0° to 360°. The UVIR type plate can be adjusted to an arbitrary phase retardation in the range 150 nm - 6000 nm and the FIR type in the range from 1 µm to 21 µm . The MULTIPHASE plate successfully replaces the expensive Soleil-Babinet and other types of compensators and can be used to analyze the state of light polarization.
The required phase retardation is achieved by tilting the plates 0° - 25° using a special tilt holder. Each plate is provided with tuning curves that allow easy determination of the phase retardation.
The variable phase retardation plates are indispensable in research with widely tunable or broadband laser sources like dye lasers, optical parametric generators and femtosecond lasers.
The variable phase retardation plates are offered at very competitive prices, making them an attractive alternative to other types of phase compensators.
