POLARCOR™ Glass Polarizers

Product catalog summary

Product Overview
Corning® Polarcor™ is a high-performance glass polarizer known for its excellent optical performance, compact size, and durability. It is used across various markets including telecommunications, aerospace, defense, and medical sectors. Key functions include creating or blocking polarized light, reducing glare, enhancing image contrast, modulating energy, and improving signal-to-noise ratio.

Applications

Polarization-dependent optical isolators
Infrared sensors
Instrument filters
Modulators
Fiber polarizers
Magnetic anomaly detectors
Various fiber optic devices

Technical Specifications
Polarcor operates effectively within the 600 nm to 2300 nm wavelength range, characterized by high extinction and low insertion loss. The polarization mechanism involves resonant absorption by elongated silver crystals, ensuring the elimination of stray light. It is resistant to chemical, physical, and thermal damage.

Performance Data
Typical performance data for wavelengths from 633 nm to 2100 nm include:

Extinction Ratio: > 10,000:1 to > 100,000:1
Transmittance: > 76.5% to > 98.5% with AR-Coating
Insertion Loss: < 1.16 dB to < 0.06 dB with AR-Coating
Refractive Index: 1.5210 to 1.5020
Reflectance: < 0.4% to < 0.25%

Product Variants

Polarcor™ W I D E Band™: Offers wide polarization bandwidths and high extinction ratios.

POLARCOR™ Glass Polarizers Product Information Specialty Materials Corning® Polarcor™ is a high performance glass polarizer, featuring excellent optical Polarcor is a keystone optical element in polarization-dependent isolators, optical modulators, polarimetry systems, ellipsometers, shutters and many other polarization-based devices. Polarcor is characterized by high extinction and low insertion loss throughout the 600 nm to 2300 nm wavelengths. The polarization mechanism (resonant absorption by elongated silver crystals within the glass material) ensures the elimination of stray light, by absorbing the unwanted polarization. Since Polarcor is a solid glass product it is extremely resistant to chemical, physical and thermal damage, while exhibiting excellent optical properties. performance, compact size and unmatched durability, that meets the most stringent requirements of the telecommunications, aerospace and defense, medical and many other markets.
