True Zero-Order Waveplate

Cemented True Zero-Order Waveplate                     


The true zero-order waveplate means that the thickness of waveplate is very thin (less than 0.1mm) which make the true zero-order waveplate excellent in temperature, wavelength and incident angle (about 20º) bandwidth. Therefore, it is excellent choice for the highly accurate application. It is cemented with a block of glass which is limited to low and medium power application.                            


Specifications:                           
Material: Crystal Quartz                 
Dimension Tolerance: +0.0, -0.2 mm     
Wavefront Distortion: < λ/8 @ 632.8 nm        
Retardation: λ/8, λ/4, λ/2 or λ (typical)             
Retardation Tolerance: < λ/200 (typical)              
Wavelength Range: 400-2100 nm             
Parallelism: <1 arc second             
Surface Quality: 20-10 scratch and dig              


Single Plate True Zero-Order Waveplate             

In order to enable the waveplate suitible for high damage threshold (more than 1GW/cm2) application: Tempotec provides a single plate of true zero-order waveplate. The thickness of this waveplate means handling can be difficult, we can provide mounts upon request.
