激光元件公司最近推出一种称为LIE309的大面积热释电探测器。该探测器的敏感元件为钽酸锂,其直径达8mm,出厂时配有氟化钙窗口以获得更好的光谱响应。由于该探测器具有如此大的敏感面积,因此适合于测量大功率激光器的辐射功率。作为选择,该探测器也可以配置其它 Laser Components recently introduced a large area pyroelectric detector called the LIE309. The detector’s sensing element is lithium tantalate, which has a diameter of 8 mm and is shipped with a calcium fluoride window for better spectral response. Due to the detector’s large area of ​​sensitivity, it is suitable for measuring the radiated power of high-power lasers. Alternatively, the detector may also be configured otherwise
