Lateral Effect Position Sensor Chapter 2 Description The PDP90A is a two-dimensional, tetra-lateral position sensing detector (PSD) that provides X and Y-axis positional information. It is designed to work with Thorlabs’ KPA101 K-Cube Auto-Aligner. This sensor can be used for general alignment purposes, as well as precise position measurements. -

X and Y from the four electrodes when incident light is applied to its surface. In addition, the PDP90A is a continuous position-sensing detector, which derives position by dividing photo-generated electrons within their substrate, rather than by profiling the intensity distribution on the surface as with segmented detectors. -

4 V. Outputs above 4 V will saturate the system, causing unreliable readings. The software will indicate the voltage level on a slide bar, and is available for download online at thorlabs.com. To reach the download page go to Services, Downloads, Detectors, and then Position Sensing Detectors and click on the link. - Page 7 Lateral Effect Position Sensor Chapter 2: Description Low power levels should be used for the position sensor. For the PDP90A, the max photocurrent is 40 µA. Using the photosensitivity curve below (Figure 2), the system saturation power can be calculated as: 40 μ...
