Features/Applications
Extreme polarization purity, very broadband,
air spaced design for high damage threshold,
exit apertures provide for safe
escape of rejected polarization

500 W/cm2 CW, 4 J/cm2 with 10
nsec pulses, typical (uncoated)

Very high polarization purity,
large acceptance angle, compact design,
less expensive than calcite polarizers

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

Large apertures available,
for lower power laser applications

1 W/cm2 CW, 0.2 J/cm2 with
20 nsec pulses, visible, typical

Tp >95%

High polarization purity and transmission efficiency
over a narrow band, cemented prism pair,
for moderate power lasers
