Plate polarizers with coatings provide very high extinction from a single plate configuration. PP45 Series standard polarizers incorporate a 45o angled, coated optic mounted in a ported cell. Precision mounting methods insure stress-free high performance. The housing design incorporates an offset input ceramic aperture, the internal beam path and mechanical center lines are coaxial.
Plate type polarizers (PP) offer several advantages over crystal or cemented cube Polarizing Beam Splitters (PBS) . Advantages include cement free, higher average and peak power handling, superior wave front quality, lower cost, low back scatter reflections, 90O S-polarization reflection. Larger apertures are possible. The main disadvantages are the limited bandwidth and beam displacement. Extinction values typically exceed 37 dB (5,000:1) at the center wavelength.
FastPulse Technology also offers a full line of Pockels cell models.
