Founded in Dayton, Ohio, ISSI has been providing innovative instrumentation systems and components in the areas of fluid dynamics, aerodynamics, combustion analysis and pressure measurements since 1995. Their line of lens control systems are ideal for machine vision, surveillance, inspection systems, event monitoring, particle shadow velocimetry systems and pressure sensitive paint systems.
How Can Lens Control Help in Your Application?
As most machine vision cameras do not come with built in lens control, this added accessory can make all the difference in your vision system. The ISSI EF lens control system can be used with any camera for full control of the lens focus and aperture. You need only attach the lens adapter and lens controller to your camera and lens for operation.
This accessory allows the user to fully control the focus and aperture, when it would otherwise be in the control of the camera. This can be written inti existing software for Windows and Linux via API commands.
Operates Canon EF/EF-S, Sigma and Tamron EF lenses
Accurate and repeatable control of focus and aperture
Auto-detection of attached lens and f/stops
Programmable preset capability
10/100Mbps Ethernet interface
Lens drift compensation
TCP/IP API command control for integration or simple GUI
Standard lens mounts are available for the adapters. For cameras with non-standard mounts, customization of the lens adapter is available at an added cost. If the flange focal distance does not equal 44.0 mm with the lens adapter and camera, a separate adapter will be needed or a custom lens adapter will need to be constructed.

Made specifically to fit Photron mini-series fast cameras. front side of the adapter features an EF adapter ring to lock lens in place and pins to make contact with the pads on lens. The back side is a male M42x0.75 mount which threads directly into a camera lens mount.
M42x0.75 18 Optical Thickness (mm) Camera Back Focal Distance (mm) 26
The T mount is a common lens mount for and other optical assemblies. This thinner 18mm thick, used for applications involving filter of the image sensor. The front side of the EF adapter ring to lock the lens in place and pins to contact with the pads on the lens. The back side is a M42x0.75 metric threaded screw mount which threads into a camera lens mount.
M42x1.0, 32 Optical Thickness (mm), Camera Back Focal Distance (mm) 12
A popular mount for medium to high resolution image sensors, the M42-mount is a 42 mm threaded optics mount. The front side of the adapter features an EF adapter ring to lock the lens in place and pins to make contact with the pads on the lens. The back side is a male M42x1.0 metric threaded screw mount which threads directly into a camera lens mount.
EF Zoom Controller
The Ethernet EF Zoom Lens Control System is used to operate all features of an EF zoom lens. The control system features a zoom control housing (LC-PZA2) and lens adapter (LC-2A-XXX) to connect to and remotely operate an EF lens. The zoom control housing contains a stepper motor and control system to read and operate the zoom, focus and aperture of an EF zoom lens. A lens grip externally holds the zoom ring of the lens so the controller can change zoom position. The control housing mounts with a standard optical mount (1/4”-20 or M6). The control box features screw and lock connections for lens adapter and power and an Ethernet connection for communication. RS-232/422/485 serial or I²C communication protocols are also available. The LC-PZA2 controller is compatible with all LC-2A-XXX lens adapters.
Integrated EF Lens Controller
The Integrated EF Lens Controller is a compact version of the EF lens controller used to operate all features of an EF zoom lens. The entire lens control system is built into the adapter housing, eliminating the need for a separate control box. The Integrated EF Lens Controller is designed with system integrators in mind to provide minimal components as well as an industrial RS-232/422/485 serial or I²C communication interface. Commands for the controller can be written into existing software for both Windows and Linux via ASCII-based commands. The controller fits a variety of camera interfaces and can also be customized to fit a specific camera body.
