OASIS-4i Controller  

The Objective Imaging OASIS-4i controller is a PCI compliant plug-and-play board that provides control of up to four micro-stepping motors.  This allows precise movement of XY stages and focus mechanisms (the Z axis), and the fourth axis controller allows for automation of extra peripheral devices such as filter wheels.

OASIS-4i is a complete, self-contained solution.  No additional power supplies are required--just install the board into a Windows PC, connect the appropriate cables and you are ready to move XY stages, focus motors, and other peripheral devices.

Key Benefits

• Universal controller, compatible with stepper-based stages including Ludl Electronics Products, Märzhäuser Wetzlar, and Prior Scientific
• PCI-compliant for easy installation and high-speed interface
• Microstepping for fast, precise operation
• Internal to PC for small footprint
• Low cost, no extra power supply needed

OASIS-AF Module

The Objective Imaging OASIS-AF is an optional daughter board that plugs into the Objective Imaging OASIS-4i controller, providing high performance processing of monochrome, composite, and Y/C video signals for real time calculation of degree of focus.  

The OASIS-AF algorithms work in concert with the OASIS-4i controller for fast autofocus operation as well as advanced measurements such as detected field area.

Since these measurements are made directly in the automation controller at video rates, the PC software does not need to grab the image or process it further until the board has determined that the image is in focus and contains useful detail.  

Scanning applications benefit greatly from the enhanced throughput provided by on-board video processing for autofocus and blank field detection. 

Key Benefits

• Compatible with standard video (NTSC, PAL, SECAM)
• Real-time autofocus information
• Real-time blank field detection
• Daughter board to OASIS-4i for minimum footprint
• Programmable for user-defined settings

Software

The full capabilities of the OASIS control hardware are accessed via high-level functions in our standard Windows DLL, or optionally using our ActiveX components for very quick up-time.

OASIS Control DLL

For transparent system integration, our control DLL simplifies the task of automation control by:

• Managing critical set-up and maintenance tasks of the OASIS-4i controller and OASIS-AF AutoFocus module 
• Providing easy-to-use functions for positional control by employing a real-world co-ordinate system
• Organizing functions according to application-specific tasks, such as stage control and automatic focus

OASIS ActiveX Controls

Optionally available are a powerful set of ActiveX controls that provide a rich set of functionality for not only basic hardware control, but also advanced scanning and user-interface elements that further simply automated applications. 

For instance, to allow free movement of an XY stage via software, simply drop the Objective Imaging SoftJoystick control onto a Visual Basic form and immediately start driving!

Furthermore, the OASIS ActiveX library contains a powerful scan pattern generator, allowing immediate creation and execution of rectangular, circular, cross, random, and user defined scanning patterns.

Whether your goal is seamless integration into a flagship automated imaging system, or customized operation for a unique application, Objective Imaging's complete range of automation control software ensures you are fully utilizing the OASIS line of automation control products with minimal effort.
