Ice Cube - Wire Grid Polarizing Beam Splitter

Ice Cube - Wire Grid Polarizing Beam Splitter

KEY FEATURES
  • Wide angle of incidence range
  • Uniformity over wide range of angles
  • High contrast and transmission over wide range of angles
DESCRIPTION
Meadowlark Optics is now the exclusive provider of the ICE Cube™ formerly offered by Moxtek.  This polarizing beam splitter (PBS) cube is optimized for use over a wide range of acceptance angles while maintaining color 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 polarizer performance exceeds that for the commonly used thin film MacNeille cubes in both acceptable wavelength range and angle of incidence range while providing more than twice the contrast ratio in the transmitted beam for most wavelengths.
 
The ICE Cube is assembled by embedding our polarizing beam splitter plate between two AR coated glass prisms. These cubes are designed with Nanowire® grid structures centered on the hypotenuse of the ICE Cube. The ICE Cube PBS separates natural light into two main orthogonal, linearly polarized components; the p-polarized light which is transmitted while the  s-polarized light is reflected at a 90? angle. In principle, half of the incident light is reflected, and the other half is transmitted.
