Product Name: Tellurium Dioxide (TeO2) Crystals for Acousto-Optic Modulators Shipping: FedEx, DHL, UPS... Currency: USD, Euro, RMB Trademark: FineWin Transport Package: Box Specification: customerised Origin: China Product Description TeO2 is a kind of acousto-optic material with high quality factor. It has good properties of birefringence and optical rotation with low velocity of propagation along (110) axis.Under the same clear aperture, the acousto-optic device produced by TeO2 crystals has the advantages of the orders of magnitude improvement in resolution, fast response speed, small driving power, high diffraction efficiency, as well as stable and reliable performance.TeO2 crystals are ideal single crystal material used to produce different kinds of acousto-optic device, such as acousto-optic deflector, modulator, resonator and tunable filter.Application:TeO2 crystals can be used to produce kinds of acousto-optic device, such as acousto-optic deflector, acousto-optic Q-switched and SAWD. Thus, these crystals are widely used in lidar, the scanning of TV and large screen's displayer, the optical memory of photon computer and laser communication.We can provide 2inch, 3inch 4inch TeO2 ingots and all specs of wafers,bars, and blocks. Any of your questions and comments are warmly welcome.Characteristic:TeO2, Colorless synthetic single crystal, grown from melt with Czochralski methodSymmetry: Tetragonal, 422 (D4)Lattice distances: a = 4.8122 A; c = 7.6157 AMolecular weight: 159.5Density, g/cm3: 5.99 ± 0.03Melting point: 7330СHardness: 3 - 4 Moh's hardness scaleThermal expansion, ·10-6К-1: α11= 17.7; α22= 17.7; α33= 5.5Transmission: 0.35 - 5.0 μmRefractive indexes:λ, μmnoneΔn = ne- no0.40472.43152.61670.18520.43582.38342.55830.17490.46782.34782.51640.16860.48002.33662.50360.16700.50862.31502.47790.16290.54612.29312.45200.15890.58932.27382.42950.15570.63282.25972.41190.15220.64382.25622.40860.15240.6902.24502.39550.15050.8002.2262.3730.1471.002.2082.3520.144Optical activity, along [001]:λ, μmp, deg/mmλ, μmp, deg/mm0.3698587.10.5893104.90.3783520.60.632886.90.3917437.40.70067.40.4152337.60.80048.50.4382271.00.90037.40.4630221.11.0029.50.4995171.21.1023.80.5300143.4Dielectric permittivity: ε11= 22.9; ε33= 24.7Elastic constants, ·10-10N/m2: c11=5.57; c33=10.58; c44=2.65; c66=6.59; c12=5.12; c13=2.18Photoelasticity coefficients: λ = 0.6328 μmp11=0.0074; p12=0.187; p13=0.340; p31=0.0905; p33= 0.240; p44= - 0.17; p66= - 0.0463Acoustooptical properties: λ = 0.6328 μmNsoundUsoundVsound,·103м/сNlightElightM1,·10-7см2·с/гM2,·10-18с3/г[100][100]2.98[010][100]0.0970.048[100][100]-[010][001]22.910.6[001][001]4.26[010][100]14234.5[001][001]-[010][001]11325.6[100][010]3.04[001]optional3.701.76[110][110]4.21[-110][110]3230.802[110][110]-[-110][001]16.23.77[101][101]3.64[-101][010]10133.4[010][010]2.98[-101][101]42.620.4[110][-110]0.617[001]optional68.6793[101][-101]2.08[010][100]76.477Photos:
