Product Description

Super Achromatic Waveplate Flat Retardance Over A Super Broad Spectral Range

Overview:

Super Achromatic Wave plate (Retarder) consists of three achromatic waveplates (made of quartz, MgF2 and sapphire) that optically cemented to maximize transmission and carefully aligned to minimize the wavelength dependence of the retardance based on Pancharatnama's design is used for modulator in polarimeter.

Comparing to the normal achtomatic waveplate which consists of one quartz plate and one MgF2 plate, the super achromatic waveplate(retarder) provides an extremely flatter retardance on a significantly broader wavelength range. 

 

 

Main Features of Super Achromatic Wave Plate: 

  • Wide spectral bandwidth
  • Low temperature sensitivity
  • Extremely flat retardance over a super broad spectral range
