Multiple Order Waveplate

Multiple Order waveplateMultiple Order waveplates are made of a single plate of laser quality crystal quartz precision polished to achieve the desired retardation at their design wavelength. They are much more sensitive to temperature and wavelengths variations than a zero-order waveplate would be. They are therefore generally useful only at specific wavelengths and operating temperatures.  


- High Damage Threshold

- Better wavefront and parallelism

- For single wavelength applications

- Low Cost
