    Low price for Aggse Crystal - Dual Wavelength Waveplates – Dien

    Dual wavelength waveplate is widely used on Third Harmonic Generation (THG) system. When you need a NLO crystal for type II SHG (o+e→e), and a NLO crystal for type II THG (o+e→e), the  out put polarization from SHG can not be used for THG. So you must turn the polarization to get two perpendicular polarization for type II THG. Dual wavelength waveplate works like a polarizing rotator, it can rotate the polarization of one beam and remain another beam’s polarization. Recommend Standard W...

     Fresnel Rhomb Retarders like broadband waveplates providing uniform λ/4 or λ/2 retardance over a wider range of wavelengths than possible with birefringent waveplates. They can replace retardation plates for broadband, multi-line or tunable laser sources. The rhomb is designed so that a 45° phase shift occurs at each internal reflection creating a total retardance of λ/4. Because the phase shift is a function of the slowly varying rhomb dispersion, the retardance change with wavelength is mu...

    Low Order Waveplatesare much better than the multi-order wave-plates because of its thinnerthickness less than 0.5 mm). Better temperature(~36°C), Wavelength(~1.5 nm) and incident angle(~4.5°) bandwidth and high damage thresholdmake it widely used in common application. Also it is economical. Recommend Standard Wavelength: 266nm,355nm,532nm,632.8nm,780nm,808nm,980nm,1064nm,1310nm,1550nm
