Wire-Grid PBS ICE Cube™
Nanowire ®
PBS ICE Cube Series Datasheet
NEW
Moxtek’s ICE 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 can be optimized for
high Index, Contrast, or Efficiency (ICE) and is a superior choice over MacNeille
cube designs.

ICE Cube Assembly and Performance Details
The ICE Cube is assembled by embedding our polarizing
beamsplitter plate between two AR coated glass prisms. These
cubes are designed with Nanowire® grid structures centered on the
hypotenuse of the ICE Cube.

Unpolarized Light
Polarized Tp
ICE Cube Polarizing beamsplitters (PBS) separate 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˚ degree angle. In principle, half of the incident light is reflected
and the other half is transmitted.
