  • Dual flexure Yaw and Pitch stages provide extreme resolution without arc error.

Superior Performance
Luminos I4000 Z/RYP Manual Positioner

Imagine a positioning system so stable and easy to adjust that aligning singlemode fiber optical fibers is as simple as tuning a radio.  No need to let go of the micrometers while adjusting - the I4000 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 I4000 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 I4000 is extremely vibration and temperature insensitive. In an ordinary lab without an optical table, normal temperature fluctuations result in only 0.03 dB variation with no drift in a typical singlemode alignment for over a month.  See Positioner Stability for more information.

Automation

With this advanced design, upgrading to automation is easy and inexpensive. The Z axis provides a larger 12.7 mm (0.5") of travel on the focal axis and a step size of 100 nm (4µ-inch). 0.2 arc seconds of resolution is available on the pitch and yaw axes and an incredible 0.1 arc seconds on the roll axis.
