Product Description
Low (multiple) order waveplate is designed to a retardance of several full waves, plus the desired fraction. This resture in a single ,physically robust componet with desired performance .However ,even small change in wavelength or temperature will result in significant changes in the desired fraction retardance .They are less expensive and find many application where the increased sensitivities are not an important.

Product Feature
The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction, Zero order waveplate shows better performance than multiple order waveplates .it has broad bandwidth and a lower sensitivity to temperature an dwaveplate changes. It should be considered for more critical applications. Standard Wavelength :355nm 532nm 632.8nm 780nm 808nm 980nm 1064nm 1310nm 1480nm 1550nm 1,zero order waveplate -Optically contacted: This type of zero order waveplate is constructed of low order waveplate with their axes crossed. Thus ,the effect of the first plate is canceled by the second, except for the residual difference between them. Optically Contacted ,AR Coated, R 90% Coating: AR coating Mount: Black Anodized Aluminum 1,True Zero Order Waveplate-single plate: This type of zero order waveplate is designed for high damage threshold application As the plate is very thin ,it's easy to break during operation . 2,True Zero Order Waveplate-single cemented :This type of zero order is constructed of a true zero order waveplate and a BK7 substrate .As the waveplate is very thin and easy to be damaged ,the BK7 plate's function is to strengthen the waveplate. 3,True Zero Order Waveplate-High power: This zero order wave plate consist of true zero wave plate and BK7 substrate ,We use special optical contact technique to assemble them. So this type plate has high damage threshold.
