OLCHING, Germany, Dec. 18, 2012 — For optical bench applications, Laser Components GmbH has introduced the P-CUBE photodiode modules, which deliver precise measurement technology in a compact setup. Low-noise, sensitive PIN photodiodes are housed in cubes that have an edge length of 40 mm. For integration into optomechanical setups, they can be attached to a rod system. Available are a GaP photodiode (190 to 570 nm), a Si photodiode (200 to 1050 nm) and an InGaAs PIN photodiode (800 to 2200 nm). The photocurrent is obtained using a BNC connector. The P-CUBE also is available with an optical FC connector. The programmable iAMP-700 current amplifier is directly connected to the P-CUBE with a BNC connector. It is possible to achieve amplifications of 102 to 1011 V/A with the iAMP-700. By combining the P-CUBE and iAMP-700, the smallest amount of light can be detected reliably. The iAMP’s electromagnetic-compatibility housing allows application in proximity to the source. The P-CUBEs require a bias voltage between −10 and 10 V, obtained directly from the iAMP.
