Product Description

Product Description
Rochon prism is a type of birefringent optical component used to separate a beam of unpolarized light into two orthogonally polarized components. It achieves this by exploiting the double refraction property of certain crystals.

Key characteristics:
- Birefringence: The prism exhibits different refractive indices for light waves that vibrate in different planes.
- Orthogonal polarization: The two output beams are polarized at right angles to each other.
- High extinction ratio: The prism effectively suppresses the polarization component that is not desired.

Applications
- Polarization microscopy: Used to examine the polarization properties of materials, such as crystals and biological samples.
- Laser systems: Employed to separate different polarization components of laser beams, enabling polarization control and isolation.
- Optical communication: Utilized in optical fiber systems to manage polarization-dependent effects and improve transmission quality.
- Optical metrology: Used for precise measurements of polarization parameters, such as polarization state and degree of polarization.
- Optical information processing: Employed in devices like liquid crystal displays (LCDs) and polarization-based optical data storage systems.
