Overview

Superior Performance

Imagine a positioning system so stable and easy to adjust that aligning singlemode fiber optical fibers is about as difficult as tuning a radio!  No need to let go of the micrometers while adjusting - the ZRYP4000 is extremely touch insensitive.  And with the patented ergonomic inline design, all the micrometers are easily accessible on one side - just rest your hand comfortably on the table and enjoy the ease and efficiency of quickly aligning any type of fiber.  No fiber alignment challenge is too difficult - even 1-2 micron core lensed fibers can easily be aligned. This is possible because of the radical departure from conventional design.

Innovation

Conventional stacked stages have separate frames with each frame simply mounted on the output of the previous stage. This results in the stiffness at the micrometer being degraded by the lack of stiffness between the mounting reference and output of each stage below it.  Hand forces on the micrometer are then easily transmitted directly to the output causing the the alignment to wander and typically results in a adjust, release, and wait cycle by the operator.  The ZRYP4000 consists of only 2 frames.  The Z stage is one frame while the rotational axes are anchored to a shared fixed frame that is attached directly to the output of the Z stage.  The Z stage is exceptionally stiff and therefore is not a factor.  By sharing a common rigid frame, forces exerted on the micrometers by the operator during adjustment are transmitted directly to the base instead of to the output.  The operator can then quickly align without letting go.  It really is as easy as tuning a radio!

The ZRYP4000 is also vibration and temperature insensitive.  Internal damping eliminates many of the resonance effects typically associated with flexure stages.

Accessories

With accessories ranging from fiber array holders to contact sensors, Luminos can get you out-fitted and up-and-running quickly on your applications.

Automation

With this advanced design, upgrading to automation is easy and inexpensive with our standard, low cost stepper motor option.  The Z axis provides a large ½ inch (12.5mm) travel on the focal axis with a resolution of 0.1 micrometers.  The same gives a resolution of 0.2 arc seconds on the pitch and yaw axes and an incredible 0.1 arc seconds on the roll axis.

A kit (Part#:ACTKIT) is required for each automated positioner. It includes a software CD, a power adapter, a USB serial port adapter (in case your PC has no serial ports available) and the necessary cables. The CD includes ActiveX/COM software which provides a simple interface from LabVIEW 6i/8+/2010, Visual Basic 6, Visual C++ 6.0, or any .NET language.

Variations

Any subset of roll, yaw, and pitch are also available.  Contact us if you require a combination not shown here.
