Superior Performance

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 I3005 is extremely touch insensitive. 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.


The Luminos I3005 benefits from our patented Ratio Drive™ while all other stages are direct-drive. A standard micrometer, which has about 1/3 the backlash of a differential micrometer, is further improved by the 5x Ratio Drive™ resulting in a backlash of only 100 nanometers and an incredible single-sided resolution of just 5 nanometers!

The I3005 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.


With this advanced design, upgrading to automation is easy and inexpensive. The automated version delivers a resolution of 20 nanometers (0.8µ-inch) and 2.5 mm (0.1") of travel on the X and Y axes. The Z axis provides a larger 12.7 mm (0.5") of travel on the focal axis and a step size of 100 nanometers (4µ-inch).

If you require more precision and need no more than 0.5 millimeters of automated travel on the X & Y axes, consider the I3000.
