Hangzhou Shalom Electro-optics Technology Co., Ltd. NOA61 Cemented Zero Order Waveplates

• NOA61 cemented structure • High Wavelength and temperature stability • Widely selectable wavelengths: 200-2000nm for Quartz waveplates, 190-7000nm for MgF2 waveplates • Damage Threshold >0.5J/cm^2@1064nm, 20ns,20Hz • Customized Quartz Zero Order Waveplates and MgF2 Zero Order Waveplates are available A Cemented Zero Order Waveplate is comprised of two single plates made from Quartz or Magnesium Fluoride, with their optical axes orthogonally aligned. The two fundamental plates are combined using NOA61 (a UV-cured optical grade adhesive produced by Norland Products). This material is a high-quality adhesive featuring great bonding strength, high heat resistance, and excellent clarity to support optical applications under various operation conditions, and Shalom EO only apply the adhesive outside the clear aperture of the waveplates. Unlike multiple order waveplates which produce the desired retardation together with several excess wavelength shifts, Zero Order Waveplates have the advantage of producing exactly the retardation of interest. As a result zero order waveplates exhibit wider bandwith and higher temperature stability, although still being susceptible to changes in the angle of incidence. Various kinds of Cemented Zero Order Waveplates made from Quartz (wavelength range 200-2000nm), or Magnesium Fluoride (MgF2) (Wavelength range 190-7000nm) are available in Hangzhou Shalom EO, including Zero Order Half Waveplates, Zero Order Quarter Waveplates, and Zero Order Octadic Waveplates with both fast despatch and competitive price guaranteed. Other Capabilities: Wavelengths: 355nm, 532nm, 632.8nm, 780nm, 808nm, 850nm, 980nm, 1064nm, 1310nm, 1480nm, 1550nm (standard), or other customized wavelengths. AR Coated, R<0.2%
