The Basic Liquid Crystal Controller is compatible with the λ/2 Liquid Crystal Variable Retarder (#63-039) and can electrically control the retardance of a single retarder by manually changing the applied voltage. It allows the convenient, stand-alone benchtop operation of the Liquid Crystal Variable Retarders. LED voltage and frequency readouts are shown on a digital display. Additionally frequency and voltage settings of the Basic Liquid Crystal Controller can be easily stored and the system memory retains voltage and frequency settings even at power down.
液晶可变波片(相位延迟片)使用彼此间隔几微米的经精密抛光的光学平直的熔融石英玻璃窗构成。空腔充注丝状液晶材料并密封。该装置可确保超高的传输波前质量和低射束偏移,适合众多要求严格的应用。无补偿相位延迟片可提供介于 30nm - λ/2 的延迟性,而补偿型相位延迟片可在 0 – λ/2的条件下工作。
液晶分子的长轴可提供非寻常波折射率。当没有电压存在时,分子与窗口平行,获得最大延迟性当对液晶层施加电压时,分子朝施加电场的方向倾斜。随着电压增大,有效双折射率减少,导致延迟性减弱。基础液晶控制器可允许人工控制单个相位延迟片。
