Measures laser beam position and power
9 x 9 mm sensor size
320–1100 nm wavelength range
Analog and adjustable digital filters to reduce noise
Compatible with pulsed laser sources
2.5 µm minimum detectable position change
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 9x9 mm sensor size, and delivers a third signal that is proportional to the beam power.

The CONEX-PSD9 can sense the posion of lasers in the 320 to 1100 nm range.
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. Where possible, modules are also powered through the USB port. CONEX Modules include software for an intuitive GUI and are fully supported for software development with LabVIEW.
Compared to 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.
