B+W Polfilter High Transmisson Zircular Master 95mm

B+W Polarizer High Transmission Circular Master KSM MRC nano 95 mm

These high-end polarizers feature a more precisely specified polarization film, and the film pieces are specially selected. After being laminated between high-quality cover glasses, an additional grinding and polishing process is carried out. This ensures outstanding sharpness even with very fast, apochromatic lenses. The lamination technique provides long-term stability even in humid climates. The generation of Käsemann High Transmission (HTC) polarizers is made with a polarization film that has higher light transmission while still maintaining excellent efficiency. The filter extension factor is only 2 - 3, which corresponds to approximately 1 - 1.5 f-stops.
