The CONEX-PSD10GE Position Sensing Detector provides accurate XY position information of laser beams and is ideally suited for laser beam stabilization, laser tracking and general beam diagnostics. Unlike quadrant detectors, the improved tetra-lateral effect diode of the CONEX-PSD10GE is highly linear over the full sensor size of 10 mm x 10 mm, and delivers a third signal proportional to the beam power.

Different than many detectors that are tweaked for high bandwidth, the CONEX-PSD10GE has been optimized for stability and compatibility with pulsed laser beams. An analog input filter with 136 Hz cut-off frequency suppresses high frequency noise and undesired signal ringing when used with pulsed lasers. An additional digital low pass filter can be set by software in a frequency range from 0 Hz to 1000 Hz to further improve signal homogeneity.

The 883-OH adapter allows mounting additional optics in front of the detector for stray light reduction or beam attenuation. The CONEX-PSD10GE is post mountable with metric and imperial screw interfaces. It comes with a USB cable to be used for communication and power.

CONEX-PSD10GE位置传感探测器提供了精确的XY位置信息，适用于激光束稳定、激光跟踪和一般光束诊断。与象限探测器不同，CONEX-PSD10GE的改进型四边形效应二极管在10mm x 10mm的全传感器尺寸上高度线性，并提供与光束功率成比例的第三个信号。与许多为高带宽而微调的探测器不同，CONEX-PSD10GE经过了优化，以保证稳定和与脉冲激光束兼容。当与脉冲激光器一起使用时，带有136hz截止频率的模拟输入滤波器可以抑制高频噪声和不必要的信号振铃。通过软件在0赫兹到1000赫兹的频率范围内设置额外的数字低通滤波器，进一步提高信号的均匀性。883-OH适配器允许在检测器前安装额外的光学器件以减少杂散光或光束衰减。CONEX-PSD10GE采用公制和英制螺纹接口。它配有USB电缆，用于通信和供电。
