Page 4: Foreword
Paragraphs preceded by this symbol explain hazards that could damage the instrument and the connected equipment or may cause loss of data. Note This manual also contains "NOTES" and "HINTS" written in this form. Please read this advice carefully! © 2019 Thorlabs...
Page 5: General Information
If necessary, ask for replacement pack- aging. Refer servicing to qualified personnel! Only with written consent from Thorlabs may changes to single components be made or components not supplied by Thorlabs be used. All modules must only be operated with duly shielded connection cables.
Page 6: Ordering Codes And Accessories
AC-coupled versions as well as open detector versions (detector cover glass removed) of each model can be ordered on request. The APD110C (/M) is factory set to M = 10. The APD120A2 (/M) is factory set to M = 50. The APD120A (/M) is factory set to M = 50. © 2019 Thorlabs...
Page 7: Getting Started
Note If you want to use your own power supply, you can ask Thorlabs for an appropriate power con- nector cable. · Carefully unpack the unit and accessories. If any damage is noticed, do not use the unit.
Page 8: Operating Instruction
For fiber coupled applications, in case of detectors with an active area of 1 mm, fiber adapters like Thorlabs S120-xx series can be easily mounted on the optical input. The fiber adapter will accommodate multi-mode as well as single-mode fiber. For detectors with smaller active areas, in order to meet specifications, it is recommended to focus the optical signal out of the fiber onto the detector.
Page 9: Electrical Output
The optical damage threshold is 1 mW. Exceeding this value will permanently destroy the Avalanche Photodetector! 3.1.2 Electrical Output Thorlabs APD110x/120x Avalanche Photodetectors deliver an OUTPUT voltage, which is a function of incident light power , detector's responsivity (l) at a given wavelength and M Â...
Page 10: Mounting
The slim line housing comes with a removable threaded coupler that is compatible with any number of Thorlabs 1” and ½” threaded accessories. This allows convenient mounting of ex- ternal optics, filters, apertures or fiber adapters, as well as providing an easy mounting mechan- ism using the Thorlabs cage assembly accessories.
Page 11: Operation
Note Avoid saturating the amplifier! Therefore, make sure that the optical input power does not ex- ceed the saturation power level listed in specifications Attention Exceeding the optical damage threshold input power will permanently destroy the detector! © 2019 Thorlabs...
Page 12: Recommendations
Another critical point can be electrostatic coupling of electrical noise associated with ground loops. In most cases an electrically isolated post (see Thorlabs parts TRE or TRE/M) will sup- press electrical noise coupling. You should always try to identify the electrical noise sources and increase the distance to the Avalanche Photodetector.
Page 13: Maintenance And Service
The unit does not need a regular maintenance by the user. It does not contain any modules and/or components that could be repaired by the user himself. If a malfunction occurs, please contact Thorlabs for return instructions. Do not remove covers! High voltage!

Page 26: Fiber Coupling Onto Small Detector Area
For detectors with an active area diameter of 1.0 mm, a Thorlabs S120-xx fiber adapter is re- commended. In this case, the detector area will not be overfilled by the diverging beam out of the fiber tip.
Page 28: Warranty
For warranty repairs or service the unit must be sent back to Thorlabs. The customer will carry the shipping costs to Thorlabs, in case of warranty repairs Thorlabs will carry the shipping costs back to the customer.
Page 29: Thorlabs 'End Of Life' Policy
Waste treatment on your own responsibility If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.
