PDF10A2 3.2 Mounting Housing The PDF10A2 is housed in a rugged, shielded, 70.9 mm x 49.9 mm x 22.5 mm aluminum en- closure. Mounting PDF10A2 on an Optical Table Mount the PDF10A2 on an optical post by using either of the two tapped mounting holes on the side and bottom. -

(Hi-Z) loads. · Switch on the power supply. · Switch on the PDF10A2 by moving the power slider to I while the optical input is protected by the cover cap. · The maximum OUTPUT voltage swing is ±10 V for high impedance loads (>10 kW). The OUTPUT signal should stay below this maximum output voltage to avoid amplifier saturation. -
Page 9: Recommendations
LED far away from the PDF10A2 can affect power measurements at femtowatt levels. o It is not necessary to switch off the PDF10A2 when it is exposed to ambient light. The amp- lifier will saturate but, unlike photomultiplier tubes, it will not be damaged or saturated for a long period of time. -
Page 10: Operating Principle
(1.1 mm x 1.1 mm). Due to this small active area of the PDF10A2 photodiodes, it is recommended to focus the op- tical signal out of the fiber onto the detector. Because the housing is compatible with any number of Thorlabs 1” and ½” threaded accessor- ies, external optics, filters or apertures can be easily attached to the PDF10A2. -

5.3 Typical Frequency Response For the measurement of the frequency response, a test signal was fed through an optical chop- per and fiber-coupled to the PDF10A2 input. The output voltage amplitude was measured with an oscilloscope. PDF10A2 Typical Frequency Response... -
Page 14: Typical Spectral Noise
PDF10A2 5.4 Typical Spectral Noise Noise is being characterized by different specifications. The spectral noise of PDF10A2 was measured using a 200 kSample/s A/D converter. The power density spectrum was calculated from the sampled values with respect to transimpedance gain and detector responsivity. The optical input of the PDF10A2 was blocked. -
