Precision achromatic polymer wavelength plate (phase plate)
We provide standard λ/4 plates and λ/2 plates. These are polymer wave plates (phase plates) that accommodate a wide spectral range.
The precision achromatic polymer wavelength plate (phase plate) is made by sandwiching carefully aligned polymer laminates between two precision N-BK7 glass substrates, which are laminated together. Standard λ/4 and λ/2 plates are available for typical visible and near-infrared wavelengths. This wavelength plate (phase plate) maintains a phase shift of less than 1% even when the incident angle deviates by ±10°. Both products are fixed within a gold frame marked to indicate the fast axis. ■ Wide spectral range ■ λ/100 retardation tolerance ■ Retardation characteristics of λ/4 and λ/2 ■ High damage threshold of 500 W/cm² *The catalog from Edmund Optics Japan can be downloaded from the link below.
