The 2903 Quadrant Cell Photoreceivers is ideal when you need to measure small deviations in the position of your 900 to 1700 nm laser beam, such as that required in beam-stabilization systems. Quadrant-cell photoreceivers consist of four individual yet identical photocells positioned very close to each other. To increase the sensitivity of these photoreceivers, each of the cells photocurrents is sent to its own individual amplifier before being processed with the other photocell signals to generate top-minus bottom difference (vertical error) and left-minus-right difference (horizontal error) signals. A sum-of-all-quadrants signal is also provided for normalization purposes. These photoreceivers can operate off batteries, your own DC power supply or our Model 0901 power supply. 8-32 mounting thread. M4 metric adaptor and tool now included.


当你需要测量900到1700纳米激光束位置上的小偏差时,例如需要在波束稳定系统中测量时,2903象限光刻机是理想的。四元细胞感光元件由四个独立但完全相同的光电池组成,它们彼此位置非常接近。为了提高感光元件的灵敏度,每个细胞的光电流都被发送到各自的放大器,然后再与其他光电管信号一起处理,产生上下差(垂直误差)和左右差(水平误差)信号。为了标准化,还提供了一个包含所有象限的信号。这些光电接收器可以使用电池,你自己的直流电源或我们的0901型电源。8-32越来越多的线程。现在包括M4公制适配器和工具。当你需要测量900到1700纳米激光束位置上的小偏差时,例如需要在波束稳定系统中测量时,2903象限光刻机是理想的。四元细胞感光元件由四个独立但完全相同的光电池组成,它们彼此位置非常接近。为了提高感光元件的灵敏度,每个细胞的光电流都被发送到各自的放大器,然后再与其他光电管信号一起处理,产生上下差(垂直误差)和左右差(水平误差)信号。为了标准化,还提供了一个包含所有象限的信号。这些光电接收器可以使用电池,你自己的直流电源或我们的0901型电源。8-32越来越多的线程。现在包括M4公制适配器和工具。
