P-Iris Controller

Key features

  • Aperture, zoom, and focus control with stepper motors
  • IR filter switching - both day and night use
  • Can be used with Basler ace Classic and ace U product series with a sensor size up to 1/1.7“, CS-mount and resolution up to 12 Mpx
  • Delivered with Theia lens:
    • Theia TL1250P – Focal length 12–50 mm
    • Theia TL936P – Focal length 9–36 mm

  • Text communication protocol, LabVIEW device driver available for download

Product description

The P-Iris lens controller with a stepper motor is an interface designed for the functional connection of motorized lenses and Basler ace cameras. It allows you to electronically control focus, zoom, aperture and IR filter. Standard RS232 interface with a text protocol is used for its control. Another option is the Basler ace camera with a modified firmware that simulates the UART communication interface on the digital output.  In this case, there is only one cable for image data transmission and lens control, because the transmission of control commands from the PC takes place over Ethernet. The camera also serves as an Ethernet - UART converter.

The controller is delivered in a set with the Theia TL1250P lens (resp. TL936P or TL410P). The combination of these two components makes it possible to cover almost all transport applications, both in terms of optical properties and image resolution and quality. With the ability to control the zoom in 12–50 mm (resp. 9–36 mm or 4–10 mm) focal range, focus and aperture, this solution is designed for small detail applications (such as vehicle registration plate) or for capturing a large field of view (such as multiple lanes) under different lighting conditions. The IR filter can be also used with infrared auxiliary light at night. This illumination can be very precisely synchronized with the camera via digital camera output. Thanks to the new generation of Basler cameras, you can even use the resolution of up to 12 Mpx.

The hardware is adapted to the dimensions of Basler Ace cameras and is a compact unit designed for installation in a device or camera housing. Aluminium holder includes mounting holes with 1/4“ tripod thread and M8.
