A-CUBE-Series High Sensitivity APD Detector Modules

Transcription

1 Series Description Laser Components new A-CUBE range of APD modules has been designed for customers interested in experimenting with APDs. Featuring a low-noise silicon (or InGaAs) APD with matched preamplifier and integrated high voltage supply, the module offers everything needed to operate APDs easily and conveniently. In-built temperature compensation circuitry allows the APD to be operated at constant gain even if the ambient temperature changes. A ±12 V DC supply is all that is needed to operate the module. The optional FC connector provides a convenient method for connecting the detector to the sample using an optical fiber. Custom designed modules and OEM versions are available on request. Features High sensitivity Low noise Easy handling Compact RS-232 interface Fiber coupling (optional) Applications APD evaluation Range finding / LIDAR Optical Communication Systems Spectroscopy Fluorescence Medical 1 Laser Components, Inc.

A-CUBE10-01 and A-CUBE10-03 will saturate with high background light levels due to their very high sensitivity. Operation in environments with high background levels (e.g. daylight) is therefore not recommended. * Custom versions up to 2 MHz are available on request.
