Axo Series Polarization

As the industry leader in full Mueller matrix polarization testing, the core measurement technologies measure all possible polarization properties (the full Mueller matrix) of a sample, and key polarization parameters (polarizer properties, retarder properties, depolarization properties) are reported to the operator.

The AxoScan™ is the fastest, most powerful polarization measurement tool available as it measures all of the polarization properties (full Mueller matrix) of a sample in 30 ms. Measurements are made in a single location, typically in a 3 mm diameter beam. With beam shaping optics, the measurement area can be reduced to a few microns, or expanded to 10 mm or larger.

The AxoStep™ is the industry's first Mueller Matrix imaging microscope. A breakthrough new instrument for polarization testing, The AxoStep measures all possible polarization properties (the complete Mueller Matrix) for every pixel in an image in as little as 14 seconds. Different microscope objectives are available for measuring different sample areas.

AxoScan is used in a wide range of applications, including:

• LCD Panels (cell gap, pre-tilt, etc).

• LCD Films (polarizers and compensation films)

• Optical Components (waveplates, beamsplitters, etc.)

• 3D Display Components (3D glasses, patterned retarder elements, LC lenses)

• Biological Samples (ex. collagen alignment in tissues)

• Stress Analysis (injection molded lenses and windows)

• Reflective Devices (LCOS displays)

• Fiber Optics (PMD measurement, PM fiber alignment)


AxoStep is used in a wide range of applications, including:

• LCD Panels (cell gap, pre-tilt, etc.)

• Variation within individual pixels

• Multi-domain pixels

• Damage due to laser repair

• Micro-optical Components

• Patterned waveplates and polarizers

• Fiber optic components

• 3D Display Components

• Film patterned retarders (FPR) and FPR polarizers

• Quantitative Polarization Microscopy


The AxoScan system measures polarization properties in a single point of the sample in only 30 ms. AxoScan is the industry standard for excellence in LCD film and panel testing, and finds many other applications in testing optical components and biological samples.


The AxoStep is the industry's first Mueller Matrix imaging microscope. The system creates a full 2D map of all possible polarization properties in areas ranging from 9 mm x 7 mm down to 40 µm x 30 µm.

Panel Mapper

The Panel Mapper systems combine tilt and rotation measurements with arbitrarily large XY table, allowing complete characterization of large samples across the entire surface of large samples. All systems are engineered for clean room use and can be used in a laboratory or on the production floor.

Film Mappers

For very large film samples, such as cross-web pieces cut from the beginning or end of a full roll, dedicated FilmMapper systems allow the largest possible film samples to be tested. A vacuum film mounting plate is permanently installed in the systems.
