Waveplate

Waveplate

High resistance wave plate

The waveplates are specially coated (e.g.excellent laser resistant) with our background technology of UV, visible and near IR.
In addition, it enables to fabricate a high laser damage optical attenuator, by using a combination of 1/2 waveplate and or PBS with high laser damage threshold coating.
Further to the above, zero-order waveplates, custom-made products with different wavelengths and dimensions, and mounted waveplates are also available.

Key features

High laser damage threshold
≧10J/cm2 @1064nm
Attenuator can be fabricate in combination with PBS
