CeF3

As a good Faraday rotator single-crystals, cerium fluoride (CeF3) have attracted much attention in the field of magneto-optics due to their broad applications such as optical isolators. The magneto-optical effects of the Ce ions are known to be caused by the intra-ionic parity allowed electric dipole transition between the 4fN and 4fN-15d1 configurations.  These transitions are close to the absorption cut-off in the widely transparent fluorides, which leads to outstanding Verdet constants in the UV wavelength region. It is a good scintillation crystal with high density and short decay time. CeF3 Crystal is a suitable material in the measurements application of high counting rate, strong absorption irradiation and high time resolution process.

    Dear Sir/Madam,

    My name is An Tran, a postdoc at the Physical and Theoretical Chemistry Laboratory, University of Oxford.

    We are looking for a CeF3 (Cerium Fluoride) crystal (thickness of ~1-2 mm). The crystal will be inserted into a cavity working at 532 nm, thus anti-reflection (AR) coating on both sides of the crystal is required with a reflectivity (per surface) as low as possible (R < 0.1%).

    If your company can offer such customized crystal, could you please give us a quotation ?
    In case the AR coating process is not available from your company, please also give us the price for the non-AR coating crystal.

    Best regards,
