Optical Dichroic Polarizing Beam Splitter Cube

Optical Dichroic Polarizing Beam Splitter Cubes

Standard Beamsplitter Cube

A Standard Beamsplitter Cube is independent of polarization. The incoming light should be: 45°linearly polarized, circularly polarized or natural light. The outgoing beams are two partially polarized beams of about the equal intensities.

Non-Polarizing Beamsplitter Cube
These cubes split the energy with minimal polarization sensitivity. The polarization states are about the same for the entrance and exit beams.
Broadband Non-Polarizing Beamsplitter Cube’s hybrid coating has certain absorption but minimal polarization sensitivity. Due to the metallic nature of the hybrid coating, those cubes are not intended for use with high powerlasers.

Polarizing Beamsplitter Cube
A polarizing beamsplitter cube consists of two right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When circularly polarized or natural light enter the cube vertically, it separated into two linearly polarized beams. The transmitted beam is P-polarized while the reflected beam is S-polarized.
And when a linearly polarized light come in, it similarly divided into two beams. But the energy ratio of the two outgoing beams is depending on the polarization of the incident beam. Polarizing beamsplitter cubes are available for many laser wavelengths and broadband ranges.

A Plano Convex Lens or Double Convex lens causes light to focus to a point, while a Plano Concave Lens or Double Concave Lens causes the light traveling through the lens to diverge. Achromatic Lens are ideal for applications requiring color correction, while Aspheric Lens are designed to correct spherical aberration. Germanium Lens, Silicon Lens, or ZnSe lens are ideal for transmitting the Infrared (IR) spectrum, while Fused Silica Lens is well suited for the Ultraviolet (UV).
