Achromatic Waveplates (Retarders)
與標準波片不同,不論所用光線的波長為何,消色差波片 (相位延遲片) 都能提供恆定的相位偏移。該裝置使用兩種不同的雙折射晶體材料,以實現對波長的獨立性。波長範圍內產生的延遲相對偏移將在所用的兩種材料之間抵消。消色差波片 (相位延遲片) 的平直回應非常適合搭配使用可調式雷射、多個雷射光系統及其他諸多光譜來源。
Designed to be used at an angle of incidence of 0°, changes of ±3° will yield less than 1% change in retardance. The 11.5mm clear aperture waveplates feature an air spaced construction; the 23mm clear aperture waveplates are cemented. All Achromatic Waveplates (Retarders) are mounted in an anodized aluminum housing with the fast axis clearly indicated.
