All Polarcor polarizers are broadband antireflection coated to increase transmission of polarized light. • Extinction ratio better than 10,000:1 • High transmission • Wide acceptance angle • Low wavefront distortion • Performance exceeding polarizing cube beamsplitters, dichroic sheet polarizers, or wire grid polarizers • Less expensive than calcite polarizers Specifications Polarizing Material Borosilicate glass with aligned silver particles, n=1.523 at 589.3 nm Wavefront Distortion 12.7 : ë/4 at 632.8 nm over the clear aperture 25.4 : ë/2 at 632.8 nm over the clear aperture Surface Quality 40-20 scratch-dig Extinction Ratio Tp/Ts >10,000:1; k1/k2 >10,000:1 in the specified wavelength range Wedge 20 arc sec Transmitted Beam Deviation 2.6 arc min Angle of Incidence 0–15° Thickness 0.5 mm Dimensions Tolerance ±0.1 mm Reflectivity per Surface broadband, multilayer antireflection coating, Ravg <0.5% Temperature 400 °C maximum Durability MIL-C-675C, moderate abrasion Cleaning Non-abrasive method, acetone or isopropyl alcohol on lens tissue recommended (see page 622) Damage Threshold 1000 W/cm2 CW, 6 J/cm2 with 13 nsec pulses at 1064 nm (pass), typical 30 W/cm2 CW, 0.17 J/cm2 with 13 nsec pulses at 1064 nm (block), typical Note: Models 05P109AR.16 and 10P109AR.16 lose about 2% transmission when exposed to visible light, even for a few minutes (fluorescent light being the worst). To regain this lost transmission, leave in a container unexposed to visible light for at least 24 hours.
