The CONEX-PSD9 is a position sensing detector designed for accurate XY position and power measurement of laser beams, suitable for beam stabilization, tracking, and diagnostics. It features a 9 mm × 9 mm silicon sensor with a wavelength range of 320-1100 nm and peak responsivity of 0.6 A/W at 960 nm. The device includes a fixed 319 Hz analog input filter and a software-adjustable digital low-pass filter from 0 to 1000 Hz to reduce noise in pulsed laser applications. It has a maximum photocurrent of 500 μA and a position sensitivity of 1.5 μm at maximum power with a 20 Hz digital filter. The sensor has a 38.1 mm diameter and 17.7 mm height, and is powered via USB2.0 with an included 1.8 m cable. An 883-0H adapter allows mounting additional optics. The detector is post-mountable with metric and imperial screw interfaces.
The CONEX-PSD9 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-PSD9 is highly linear over the full sensor size of 9 mm x 9 mm, and delivers a third signal proportional to the beam power.
Different than many detectors that are tweaked for high bandwidth, the CONEX-PSD9 has been optimized for stability and compatibility with pulsed laser beams. An analog input filter with 319 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.

Simple Control Software
All CONEX modules provide easy, plug-and-play, USB PC control. Multiple units can be connected to a single USB port using standard USB hub technology. CONEX-PSD modules are powered through the USB port and includes an intuitive software. The CONEX module is fully supported for software development with LabVIEW™.
Works With Pulsed Lasers
Compared to many detectors that are tweaked for high bandwidth, the CONEX-PSD has been optimized for stability and compatibility with pulsed laser beams. An analog input filter with 319 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.
Mounting Additional Optics
The adapter/optic holder allows mounting additional optics in front of the detector for stray light reduction or beam attenuation.
