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.

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.

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.

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.

The 2901 Quadrant Cell Photoreceivers is ideal when you need to measure small deviations in the position of your 190 to 1050 nm laser beam, such as that required in beam stabilization systems.
