Polarizing Filter 80 mm, Rotary Mounted
The LINOS® Polarization Filter with an 80 mm diameter in a rotary mount is a precision thin-sheet polarizer, directly cemented between plano cover glass for robust handling and optical stability. Designed for stress analysis, polarimetry, and other laboratory applications, this linear polarizing glass filter provides reliable, consistent control of polarized light. Its sizable free aperture allows integration into a variety of optical setups, while the rotary mount provides convenient, continuous adjustment of the polarization axis. Unlike polymer films, the all-glass construction delivers superior durability, excellent optical flatness, and minimal distortion, making it well-suited for experiments requiring high polarization fidelity.
Designed for moderate light intensities and broadband illumination, this polarizing filter delivers high polarization and consistent, reproducible performance. This filter combines precision performance with practical usability, offering a versatile solution for both educational demonstrations and professional laboratories.
Thin sheet polarizer cemented between plano cover glass (no protective film) for improved optical clarity and durability
Ideal for stress analysis and polarimetry (usable wavelength range: 450–700 nm), enabling precise evaluation of birefringent materials
Large free aperture (78 mm) supports wide beam applications and uniform illumination
True linear polarization with high performance (degree of polarization >99.98%, extinction ratio ~1:9,000 @546 nm) for accurate optical measurements
High transmission (~42% for unpolarized white light @546 nm) ensures efficient light throughput
Strong contrast performance: >36.4% transmittance for parallel filters and <0.004% for crossed filters @546 nm
Glass-based design enhances stability, scratch resistance, and long-term reliability
Integrated rotary mount with 1° scale allows precise, repeatable angular alignment
Flexible mounting via central M6 thread and 2×M4 holes (50 mm spacing) for easy system integration
Temperature stable up to approx. 70 °C and compact 2.5 mm thickness for robust, space-efficient use
