Achromatic Waveplate is a special kind of Zero Order Waveplate, comprised of one single waveplate made from crystal quartz and one single waveplate made from Magnesium Fluoride (MgF2). The two birefringent materials which construct the achromatic waveplates have complementary birefringent properties that result in a virtually flat response of phase delay over a broad wavelength band (hundreds of nanometers), therefore achromatic waveplate is an excellent choice for applications orienting Tunable laser sources, Femtosecond laser systems, Spectroscopy, and other systems concerning Broadband light sources.
Hangzhou Shalom EO offers Achromatic Half Waveplates and Achromatic Quarter Waveplates made from single-crystalline quartz and magnesium fluoride (MgF2), half waveplates could be applied to the rotation of vertical polarization and horizontal polarization, whilst quarter waveplates could be used for conversion of linear and circular polarization.
The achromatic half waveplates and quarter waveplates are all configured by high-quality AR coating to minimize transmission loss. About the construction of the waveplates, the waveplates are either cemented by NOA61 (Norland Optical Adhesive 61) or with an architecture of an air gap in between. NOA61 is a high-performance adhesive, and Shalom EO only applies the glue outside the clear aperture of the waveplates. Achromatic waveplates with air-spaced designs are characterized by particularly promoted damage thresholds greater than 500MW/cm^2, and are suitable for high energy lasers.
Off-the-shelf modules of Achromatic waveplates are available for online shopping in Shalom EO. The standard type achromatic waveplates are of half or quarter retardation, with three optional wavelength ranges: 450-650nm, 690-1200nm, 900-2000nm covering the Visible, and a portion of the Infrared Spectrum, with fast delivery are guaranteed. Incidentally, If you have any other specific requirements, Shalom EO also provides custom services where all the parameters could be tailored to suit your demand.
