Request InfoThorlabs Ltd.The TQD001 T-cube from Thorlabs Ltd. features two operating modes: open and closed loop. In the former, the unit operates as a flexible position-sensing detector providing hardware and software interfaces for reading the sum and X-Y difference signals. In the latter, it can be used in conjunction with piezo T-cubes in positioning of a piezo-driven mirror in an optical system. T-cube controllers provide functional, flexible and expandable modules in a cost-effective and compact format.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2022 IssuePosition-Sensing DetectorThe high-sensitivity, 2-mm-diameter APX-PSD-XVInG-3.1 Position-Sensing Detector (PSD) from Advanced Photonix features spectral response from the visible to NIR and SWIR wavelengths.
