The Licel Si-Avalanche Photodiode Module consists of the detector head and the power supply unit. The APD module combines a Si/InGaAs-Avalanche Photodiode, TE cooler, temperature controller, preamplifier and XYZ positioner in a single compact module. APD and preamplifier are carefully shielded against RF and noise through the power lines. An external HV supply is included.

The APD can be remote controlled via Ethernet ( Remote control data sheet). See the Ethernet Connectivity page for a list of available options.

Air Cooled InGaAs APD Module

The Licel InGaAs APD detector has an air cooled TEC package. The 200 µm diameter detector can be cooled down to 0°C and is packaged using the same form factor as our Si- APD module.
