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.

Remote Control:
The APD can be remote controlled via Ethernet ( Remote control data sheet). See the Ethernet Connectivity page for a list of available options.Isolated digital interface
Starting from 2023 we ship for APD modules, which are integrated into detection systems and remote controllable with a isolated digital remote control to break ground loops.
They have a 6 pin Lemo connector
Analog interface
The analog remote control input is a good choice when the remote control is done by user hardware.
The cassette has 4 pin M8 sensor connector
Air Cooled InGaAs APD Module
The Licel InGaAs APD detector has an air cooled TEC package. The 500 µm square detector can be cooled down to -15°C and is packaged using the same form factor as our Si- APD module.
