Laser Unequal Pathlength Interferometer (LUPI-II™) Systems
Test
and Align Optics and Systems
THIS IS A POWERFUL TOOL FOR TESTING IN APPLICATION AND RESEARCH AND DEVELOPMENT LABORATORIES AND FOR OPTICS FABRICATAOR SHOPS. SIMPLE AND PRECISE OPERATION PROVIDES FOR FAST VISUAL CHECKING OF INTERFEROGRAMS BY EYE, VIDEO CAMERA DISPLAY OR VIA FRINGE ANALYSIS.
The laser unequal pathlength interferometer is a portable, precision instrument for testing and aligning optical components and systems. It can serve as the primary inspection tool for in-process optical fabrication and final quality certification. It is very compact and portable, yet extremely stable and is adaptable to most component or system tests, including coated and uncoated optics in reflection or transmission.
The
SORL LUPI Interferometer can easily be modified for phase shifting. For such an
application a piezo operated flat can simply be placed and mounted in front of the
permanent reference flat. The piezo induced phase shift in conjunction with the
appropriate camera provides fringe analysis and interferogram interpretation.
This
software supported fringe analysis system is available as an option. It permits mapping
and averaging, wavefront scanning, fringe fitting, and subtraction of aberrations and
polynomials.
