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
