LBTEK-polarization-maintaining mirror

Product Description

Maintains the polarization state of incident light with a high extinction ratio ER > 3000:1
Reflection: Rabs > 99% @ design wavelength, 45° AOI
Working wavelength: 420 nm，532 nm，671 nm，689 nm，780 nm，795 nm，813 nm，852 nm，1013 nm, optional

At an angle of incidence (AOI) of 45°, LBTEK polarization-maintaining mirrors effectively preserve the polarization state of linearly, elliptically, and circularly polarized light, while simultaneously achieving high reflectivity (Rabs > 99%). These mirrors are ideal for reflective optical systems requiring precise control over polarization and phase, making them a perfect choice for free-space optical devices in quantum precision measurements, quantum computing, and quantum communication key distribution—applications demanding strict polarization stability and beam fidelity. The LBTEK polarization-maintaining mirrors are based on ultraviolet fused silica substrates, offering 10 selectable operating wavelengths within the 420–1064 nm range and three available sizes (Ø12.7 mm, Ø25.4 mm, Ø50.8 mm). For custom requirements, please contact technical support.

LBTEK polarization-maintaining mirror, when used in reflective optical paths, can stably maintain the polarization state of incident light, making it especially suitable for optical systems that require precise control of polarization state and phase. Its carefully designed coating can effectively maintain the polarization state of incident light while providing high reflectance within a certain operating bandwidth; detailed data can be obtained from the curve. During use, please pay attention to protecting the coating, as damage to the coating will directly reduce device performance.
