London, June 25 (ANI): The eye of the peacock mantis shrimp has led to the development of a two-part waveplate that could improve CD, DVD, blu-ray and holographic technology, creating even higher definition and larger storage density.
The beam passes through optical elements including a waveplate, a cube polarizer, and a Powell lens.
If the resulting relative phase shift for a beam passing through the waveplate is equal to [PI]/2 or 90[degrees], a quarter-waveplate exists.
CVI announced today that it has introduced a 12mm clear aperture achromatic waveplate.
While other materials do exhibit birefringent qualities, the fact that the team was able to use a cellophane sample only 25-[micro]m thick, surpasses the commercial viability of a traditional waveplate, which may have significant applications in the gaming industry.
This alternative to a Faraday isolator achieves up to 20dB passive isolation of linearly polarized light by combining an optically contacted laser line polarizer cube and a multiple-order quarter waveplate.
The ABSO beamsplitter assembly utilizes an optically contacted PBSO polarizer cube and a QWPM multiple-order quartz half waveplate to achieve continuously variable transmission from 1-95% for both UV and high energy VIS-NIR lasers.
