 Epoxy Cemented True Zero Order Waveplate
 
The thickness of a true zero order quartz plate is very thin, it is very easily damaged. In order to solve this problem, we can cement the thin quartz plate on a BK7 substrate to increase the strength.
 
  • Standard Thickness: 1.1±0.2mm
  • Epoxy Cemented
  • Moderate Damage Threshold
  • Better Temperature Bandwidth
  • Wide Wavelength Bandwidth
  • RoHS Compliant

 

           λ/2 Part No.

           λ/4 Part No.

Single Plate True Zero Order Waveplate
 
Compared with cemented true zero order waveplate, single plate true zero order waveplate is only one quartz plate, it has high damage threshold. As the thickness is very thin, only 1310nm and 1550nm are available.
 
  • High Damage Threshold
  • Better Temperature Bandwidth
  • Wide Wavelength Bandwidth
  • Thickness >0.04mm
  • RoHS Compliant
