25 Feb 2011 To simplify the work involved in position measurement for a user, LASER COMPONENTS’ proven SPC PSDs, from SiTek, are available with an evaluation board.
The SPC electronics features four individual transimpedance preamplifiers (two each for both X and Y axes) as well as sum and difference amplifiers for each direction. The PSD currents are converted to bipolar voltages, which represent the position and intensity of the centre of the beam on the sensitive surface of the PSD.
Position Sensing Detectors have the advantage of higher resolution and speed when compared to CCDs and CMOS detectors.
The inexpensive signal processing circuits are available in a compact design together with different one and two-dimensional Silicon PSDs.
The evaluation board makes the handling of PSDs even easier. The detector, mounted on a small PCB, can be fixed to an optical bench. All incoming and outgoing signals are connected with a 14 pol connector.
