Achromatic Depolarizers
Two Wedged Prisms: Made from birefringent materials with a 45° offset.
Variable Path Lengths: The wedges cause varying path lengths through each prism, resulting in net birefringence and a final polarization state dependent on spatial variations.
Randomized Polarization: Converts polarized light into a pseudo-polarized state, ideal for beams of large diameter.
Crystal Quartz Construction: Durable and reliable material with excellent optical properties.
Applications: Optical Systems, Scientific Instruments, Laser Systems, etc.
An Achromatic Depolarizer is a sophisticated optical component that consists of two wedged prisms made of birefringent materials, typically crystal quartz, with their fast axes aligned at a 45° angle to each other. One prism is twice as thick as the other. This design transforms polarized light into a pseudo-polarized state, meaning the polarization of the incident beam is randomized rather than converted into a completely unpolarized state.
