Patented Technology

ORISANDO® SVRs are engineered using patented direct laser writing technology (Patent no. WO2019244120A4, Manufacturing Method of Spatially Modulated Waveplates).

This proprietary technique enables the formation of self-organized nanogratings within the bulk of fused silica, resulting in exceptionally stable, precise, and laser damage-resistant birefringent structures. 

Unlike conventional thin films or surface coatings, these bulk nanostructures maintain superior optical stability even under demanding conditions.

Exceptional Accuracy and Design Freedom

Each ORISANDO® SVR is built with tailored birefringent properties that can be controlled with nanometric precision across five degrees of freedom:

• Spatial positioning of birefringent zones
• Retardance magnitude and modulation pattern
• Orientation of the birefringence axis
• Aperture geometry and beam profile control
• Depth and structural density adjustments

This versatility allows ORISANDO® to produce flat optical elements capable of manipulating light’s polarization, phase, and amplitude with unparalleled precision and reproducibility.

Ideal for High-Power Lasers and Ultrafast Laser Applications

ORISANDO® SVRs exhibit ultra-high laser-induced damage thresholds (LIDT), making them ideal for integration into high-power laser systems used in:

• Precision materials processing
• Laser micromachining
• Spectroscopy and imaging
• Optical communications
• Beam shaping and depolarization correction

Their internal birefringent nanostructures ensure long-term stability, minimal scattering, and outstanding transmission performance even in femtosecond and nanosecond laser environments.
