Cemented Zero Order λ/2 Half Wave Plate, High Retardance Overview: Cemented zero order wave plate is constructed by two quartz plates with their fast axis crossed. The two plates are cemented by UV epoxy. The difference in thickness between the two plates determines the retardance. Zero order waveplate features better performance than multiple order waveplate, as zero order waveplate has lower sensitivity to temperature and wavelength changes. Main Features of Cemented Zero

Cemented Zero Order λ/4 Quarter Wave Plate, High Retardance Overview: Cemented zero order wave plate is constructed by two quartz plates with their fast axis crossed. The retardance is determined by the difference in thickness between the two quartz plates. The main difference between cemented zero order waveplates and other kind of waveplates is they have epoxy on its optical path as the two quartz plates are glued with each other by UV epoxy. However, cemented zero order

Super Achromatic Waveplate Flat Retardance Over A Super Broad Spectral Range Overview: Super Achromatic Wave plate (Retarder) consists of three achromatic waveplates (made of quartz, MgF2 and sapphire) that optically cemented to maximize transmission and carefully aligned to minimize the wavelength dependence of the retardance based on Pancharatnama's design is used for modulator in polarimeter. Comparing to the normal achtomatic waveplate which consists of one quartz plate

True Zero Order λ/4 Quarter Wave Plate, Large Feild Angle, for imaging systems Overview: Comparing with normal two plates design Zero order waveplates having a relatively larger thickness which reduces the field angle, the True zero order wave plates are made of a very thin plate or cemented with a BK7 substrate, which ensures the best possible field angle, temperature and wavelength performance. If the angle between the electric field vector of the linearly polarized

Multiple Order λ/2 Half Wave Plate, High Damage Threshold, Low Cost Overview: Multiple Order Wave plate means the fact that the retardance of a light path will undergo a certain number of full wavelength shifts in addition to the fractional design retardance. Half Wave Plates are typically used to rotate the polarization of light. The net effect of multi order waveplate at the design wavelength is basically the same as zero order waveplate. But the optical bandwidth is

Achromatic Λ/2 Half Wave Plate, Wide Spectral Bandwidth For Tunable Lasers Overview: Zero-Order Achromatic Wave Plates (Retarders) are constructed by aligning the fast axis of a birefringent quartz plate with the slow axis of another birefringent plate made from magnesium fluoride or UV sapphire, resulting in a relative phase delay of λ/2 or λ/4 between the two axises. Half Wave Plates can rotate the polarization plane of linearly polarized light. The relative shifts in
