Very Precise Control of Axis Orientation

We provide very accurate control for axis orientation of polarizers and waveplates, which can be tuned finely over the surface, in areas as small as a 1μm.

Photonic Crystal

High-Power
High Heat Resistance

The components are made of inorganic materials, making them very resistant to high-power light input. They are also heat-resistant, having almost no temperature dependence.

高い耐光性・耐熱性

Photonic Crystal

Outstanding
Optical Properties

With optional Anti-Reflection (AR) coatings, the elements exhibit very small absorption & diffusion, while providing high transparency. Moreover, phase plate elements are True-Zero Order, making them ideal for applications requiring small wave front perturbation, while providing very small dependence on incident angle.

Deep Ultra-Violet (DUV) Polarizers and Phase Plates

Deep Ultra-Violet (DUV) Polarizers and Phase Plates

The operating wavelength can be selected as short as 250nm in the deep UV range. Due to their inorganic nature, our polarizers and phase plates are very resistant to high-power light input, even in the DUV range.

Half-Mirror Polarizer for Laser Cavity

Half-Mirror Polarizer for Laser Cavity

Reflectivity for each polarization can be tuned separately. As a half-mirror in a laser resonance cavity, the element is used to generate and select the output polarization of the laser. Because of its inorganic nature, the element can withstand very high optical power.

Custom Polarizer & Phase Plates

Custom Polarizer & Phase Plates

Our products can be customized not only for the optical properties, but also for the shape and the spatial distribution of those properties. In particular, they can be made non-uniformly, having a segmented structure or a curved axis along the surface. Pease feel free to discuss any exotic design you may need for your application!
