CVX Aperture Control

Aperture Control via RS232 interface

Using the CVX Aperture control, a voltage-controlled aperture can be driven via the PCs RS232 interface.

An external control desk for the aperture is not required as the control is easily achieved from the computer. For control tasks, the demo software can be used (which is supplied) and this can also be used for custom applications to address the controller directly via a simple protocol.


  • Power: 12 - 24 Volt DC / approx. 50 mA
  • Output control voltage Iris: 1,5 - 5,5 Volt DC
  • Output supply voltage Iris: 10 Volt DC/ max. 40 mA
  • Tolerance (setting the aperture; depending on aperture): approx. 20 mV steps
  • Setting time for the aperture (depending on aperture): approx. 1,5 sec
  • Supported lenses: all lenses with a control input of 1,5 - 5,5 Volt DC
