Deep Ultraviolet Polarizer
Meadowlark Optics is pleased to offer several polarizer and retarder options that work in the ultraviolet region of the light spectrum.
Developed for wavelengths between 245 and 285 nm, the Deep Ultraviolet Polarizer is ideal for applications around 266 nm. Additionally, this polarizer is transparent in the visible range, allowing visible light to easily pass through.
The UV Polarizer has a proprietary structure that allows for a high laser damage threshold. A few of the applications where DUV polarizers are used include: DUV lithography and metrology, UV laser optics, semiconductor wafer processing, surface polarimetry, astronomical polarimetry, and liquid crystal photo alignment.
