Review THORLABS 20mm Polarizing Beam Splitter Cube 620-1000nm

The Thorlabs PBS202 is a high-quality 20 mm polarizing beam splitter cube designed for use in the wavelength range of 620-1000 nm. This beam splitter cube is an essential component for various applications in optics and photonics, including polarimetry, spectroscopy, and beam splitting.

The PBS202 is made of high-precision glass with a thickness of 2.5 mm, ensuring excellent flatness and parallelism. The cube is coated with a multilayer antireflection (MAR) coating on both surfaces to minimize reflections and maximize the transmission of the desired polarization state. This results in a high extinction ratio, which is crucial for separating the polarization components of a beam.

The polarizing beam splitter cube functions by allowing the vertically polarized component of the incident beam to pass through while reflecting the horizontally polarized component. This property is ideal for applications that require the separation and analysis of polarized light. The reflection and transmission surfaces of the PBS202 are highly polished and flat, ensuring minimal distortion of the beam and maintaining the integrity of the polarization state.

The PBS202 is compact and lightweight, with dimensions of 30.5 mm x 30.5 mm x 7.6 mm, making it convenient for use in various experimental setups. It is also easy to install and align, with a square, 20 mm mounting aperture, allowing for simple integration into standard optical mounts.

This polarizing beam splitter cube is suitable for a wide range of power levels and has a high damage threshold, making it ideal for use with powerful laser sources. The PBS202 is also compatible with various optical components and systems, making it a versatile addition to any optics laboratory or research facility.

In summary, the Thorlabs PBS202 is a precision-engineered 20 mm polarizing beam splitter cube designed for use in the wavelength range of 620-1000 nm. It offers excellent flatness, parallelism, and high extinction ratio, making it an essential component for applications in polarimetry, spectroscopy, and beam splitting. The PBS202 is compact, lightweight, and easy to install, making it a versatile and valuable addition to any optics or photonics laboratory.
