Moxtek Ice Cube Polarising Beamsplitter Cube

Wire-grid polarising beam splitter

Moxtek’s ICE Cube™ is optimised for use over a wide range of acceptance angles while maintaining colour uniformity and image contrast in the visible wavelength ranges. The ICE Cube allows compact optical designs with reduced optical paths. Engineers are now able to design smaller systems while maintaining excellent optical performance. The ICE Cube can be optimised for high Index, Contrast, or Efficiency (ICE) and is a superior choice over MacNeille cube designs.

Due to the nature of these components, there exists very few standard configurations. Therefore, please contact us to discuss your specific requirement.
