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! © 2020 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 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
An open beam should be carefully aligned to the detector. Additional focusing lenses can be easily attached to the Avalanche Photodetectors. The housing is compatible with any number of Thorlabs 1” and ½” threaded accessories. This allows convenient mounting of external op- tics, filters, apertures or fiber adapters.
Page 9: Electrical Output
Attention The optical damage threshold is 1 mW. Exceeding this value will permanently destroy the Avalanche Photodetector! 3.1.2 Electrical Output Thorlabs APD410x Avalanche Photodetectors deliver an OUTPUT voltage, which is a function Â of incident light power , detector's responsivity...
Page 10: Mounting
Thorlabs 1” and ½” threaded accessories. This allows convenient mounting of external op- tics, filters, apertures or fiber adapters, as well as providing an easy mounting mechanism 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! © 2020 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!
