  • Product Detail

    Achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range.

    Features:

    Spectrally Flat Retardance
    Operating Ranges from UV to Beyond Telecom Wavelengths
    AR Coatings for: 260 – 410 nm, 400 – 800 nm, 690 – 1200 nm, or 1100 – 2000 nm
    Quarter- and Half-Wave Plates Available
    Custom Designs Available Upon Request
