Description
Super Achromatic Waveplate is similar to achromatic waveplate but providing a flat retardance over a super broadband wavelength range. Normal achromatic waveplate consists of one quartz plate and one MgF2 plate, which has only few hundreds of nanometer wavelength range. Union Optic’s super achromatic waveplate is made from three material, quartz, MgF2 and sapphire, which can provide flat retardance on a broader wavelength range.
