Achromatic (Broadband) Waveplates. Half and quarter waveplates rotate or convert polarization over wide wavelength range with low dependance. An achromatic waveplate is an optical component that alters the polarization state of light over a broad wavelength range without introducing chromatic aberrations. Alien Photonics achromatic (broadband) waveplates ensures consistent performance in applications involving multiple or varying wavelengths, unlike standard waveplates designed for a single wavelength (True-Zero order, (effective) zero order, low-order, etc. ) Which one to choose - achromatic or super aromatic waveplate? Standard Achromatic (Broadband) Waveplates Made from two waveplates of different materials (MgF₂ and Quartz). This construction allows to achieve near-constant retardation throughout whole designed wavelength range. Super Achromatic (Broadband) Waveplates These waveplates are constructed from several waveplates and materials. Sandwich-like construction minimizes chromatic dispersion and ensures even more constant retardation throughout whole designed wavelength range Based on what you are trying to achieve – rotate polarization or convert it (linear to circular or circular to linear) you need to choose the right waveplate. Alien Photonics achromatic waveplates comes in half and quarter wave, ensuring broadband wavelength optimization. Half-wave (HWP, λ/2) Achromatic (Broadband) Waveplate Half-Wave (HWP, λ/2) achromatic (broadband) waveplate is designed to introduce a half-wavelength phase shift between two orthogonal polarization components of light over a wide wavelength range, making the phase shift nearly independent of the light's wavelength.
