Multiple order wave plate

Multiple order waveplate means the retardance of a light path will undergo a certain number of full wavelength shifts in addition to the fractional design retardance. The thickness of multi order waveplate is always around 0.5mm. Compared with zero order waveplate, multi order waveplate is more sensitive to wavelength and temperature changes. However, they are less expensive and widely used in many applications where the increased sensitivities are not critical as an essential kind of Polarization Optics. The most common Lambda/2 Multiple Order Waveplate and Lambda/4 Multiple Order Waveplate is at 1064nm and 532nm, other wavelength could be customized.

Coupletech offers multiple order wave plate with thickness is 0.3-0.5 mm, it has higher damage threshold, better temperature bandwidth, better wavefront, better parallelism and low cost. Especially, Low Order Waveplate 266nm from Coupletech is in the range of deep-UV wavelength. Coupletech provides all kinds of waveplates, besides, many kinds of polarizing optic for precision optics are available, especially, Polarization Rotator, Polarizing Filter and Polarizing Beam Splitter.
