EL-E-OF-A lens controller for EL-10-42-OF with analog interface (0-5V)

The EL-E-OF-A enables the control of the EL-10-42-OF lens module via an analog voltage signal. Several digital signals are available for status verification. The electronics provides an analog-to-digital stage to read the control and set voltage signal, digital processing with an implemented PID-loop and current sources to drive the lens and the heater unit. The board is optimized for OEM integration in laser marking systems and therefore comes without housing.

Main features:

• Analog control voltage from 0 to 5 V (ADC resolution 16 bit

• Sampling rate 1.1 kHz

• Lens driving current ranging from 0 to 300 mA

• Integrated optical feedback (OF) control

• JTAG or USB interface for firmware update

Applications

• 2.5D laser processing
