True zero order waveplates

Specifications ture zero order waveplate

1.type:half waveplate,quarterwaveplate

2.Wavefront Distortion:1/8lambda at 633nm

True Zero Order Waveplate True Zero Order Waveplate cemented This type of zero order waveplate 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. Cemented by Epoxy
Wide Angle Acceptance
Better Temperature Bandwidth
Wide Wavelength Bandwidth
AR Coated, R<0.2%   Standard Wavelength Applied:    l /4: 632.8nm,780nm,808nm,850nm,980nm,1064nm,1310nm,1480nm,1550nm 
  l /2: 532 nm, 632.8nm,780nm,808nm,850nm,980nm,1064nm,1310nm,1480nm         True Zero Order Waveplates- Single Plate

This type of zero order waveplate is designed for high damage threshold applocation (more than 1GW/cm2). As the plate is very thin, it's easy to break during operation.
