Fixed polarization state single direction polarization linear polarization lens

Fixed polarization state single direction polarization linear polarization lens is a high-precision optical element designed for application scenarios that strictly limit the polarization state of transmitted light. The lens only allows linear polarization light in a single direction to be efficiently transmitted within a specific wavelength range, while accurately maintaining a fixed polarization azimuth, effectively suppressing stray light interference from non-target polarization states, and providing stable and reliable optical control capabilities for polarization-sensitive systems.

Product Features
Precise polarization state control
Through special coating and substrate processes, linear polarization light output with high extinction ratio (>1000:1) is achieved, ensuring that the polarization direction error of the transmitted light is ≤1°.

Unidirectional polarization selectivity
The built-in asymmetric optical structure only allows linear polarization light in a preset direction to pass through, and the attenuation rate of reverse polarization light is >99.9%, significantly improving the system signal-to-noise ratio.

Thermal stability and mechanical stability
Using stress compensation packaging technology, the polarization azimuth drift is <0.5° in the temperature range of -40℃ to +85℃ and mechanical vibration conditions.

Wide-band low-distortion imaging
Optimize the multi-layer film system design to achieve wavefront distortion <λ/4@633nm in the 400-1600nm band, compatible with the requirements of high-resolution imaging systems.

Enhanced environmental robustness
The surface hard silicon carbide protective film has passed the MIL-STD-810G salt spray certification and is suitable for industrial-grade harsh optical environments.
