Laser Components has unveiled its H0 series of photodiodes receivers that are supplied in a compact, modified TO5 housing with a diameter of about 5mm.

The H0 series can be integrated into small systems that can be used for measuring distances or detecting the smallest light signals. With its H0 series, Laser Components has developed an APD receiver with an inherent noise of nearly zero. Depending on the integrated feedback resistor, a bandwidth from DC and up to 80MHz can be achieved.  If the SAR500, a Avalanche PhotoDiode receivers (APD) with a diameter of 500μm, is integrated, the module has a noise equivalent power of  4.86fW/√(Hz) at an amplification of 3 x 107V/W. With the 80μm or 200μm Indium Gallium Arsenide APD of the IAG series, the following values can be achieved: 1.1 x 106V/W @ 0.47pW/√(Hz).
