Specifications

Features

High Retardation Accuracy

Our polymer achromatic waveplates are designed to operate with a high degree of retardation accuracy over a broad wavelength range. These true zero-order wave plates are constructed using a stack of birefringent polymer films laminated between two high-precision N-BK7 optical windows, each with a high efficiency, broadband antireflection coating. This construction ensures excellent transmitted wavefront quality, while minimizing beam deviation and surface reflection losses.

Wavelength Performance of Common Quarter Waveplates

Low Sensitivity to Wavelength Change

Achromatic Zero-Order Waveplates have low sensitivity to incidence angle and wavelength. Retardation changes by less than 1% over a ±7° incidence angle and is maintained to better than ±λ/100 over the entire bandwidth. This is a significant improvement in angular acceptance and less sensitivity to wavelength change than achromatic quartz–MgF2 wave plates. One drawback however is that the achromatic waveplates have some variation in transmittance vs wavelength due to several polymer layers that are used in each achromatic wave plate. Quartz-MgF2 offer a higher and more uniform transmittance.

Black Anodized Aluminum Housing

The achromatic waveplate assembly is mounted in a black anodized aluminum housing for protection and ease of mounting, with the retarder fast axis marked for alignment reference. The standard 25.4 mm outer diameter housing has a 10.2 mm diameter clear aperture and is convenient for mounting into Newport rotation mounts.
