Optolink Polarization Beam Splitter

Optolink Polarization Beam Splitter (PBS)

The Optolink Polarization Beam Splitter (PBS) is a type of optical beam splitter designed to divide a single beam of light into two beams with distinct linear polarizations. This device is crucial in various applications where conserving the energy of the original input beam is paramount.

Key Features

• Polarization Division: The PBS splits light into two beams based on their polarization states. It reflects S-polarized beams and transmits P-polarized beams.
• Cube Configuration: Typically configured as a cube, it eliminates ghost images and ensures clean, polarized output beams.
• Dielectric Coatings: The use of dielectric coatings allows for customization for specific applications, providing control over the amount of light transmitted or reflected in the S and P polarizations.
• High-Powered Laser Compatibility: Polarizing beam splitter cubes with large damage threshold dielectric coatings can withstand high-powered laser beams.

Applications

• High-Powered Laser Systems: Used in high-powered laser applications due to their ability to withstand high-powered laser beams.
• Optical Instruments: Enhances imaging clarity by selectively allowing desirable light through, ensuring optimal visual output.
• Fiber Optics: Employed in isolators and fiber amplifiers to isolate P-/S ratios, enhancing signal control.
• LCOS Projectors: Embedded polarizing beam splitter cubes contribute to increased contrast and superior image quality in high-resolution LCOS projectors.
• Telecommunications: Used in fiber optic networks to route and distribute signals efficiently.
• Microscopy: Essential in fluorescence microscopy for separating excitation and emission light, and in confocal microscopy for splitting light between the specimen and the detector.
• Interferometry: Used to divide a single beam of light into two, subsequently combining them to create an interference pattern for precise distance measurements.

Technical Specifications

• Splitting Ratio: While non-polarizing beam splitters are specified by their splitting ratio, polarizing beam splitters are specified by their extinction ratio, which is the ratio of P-polarized light to S-polarized light in the transmitted arm.
• Polarization States: The device splits light into S-polarized beams that are reflected and P-polarized beams that are transmitted.
