Sampler attenuator PFSA / DPFSA Series

laser beam

Laser Beam Attenuation with Single or Dual Prism Front Surface Attenuators Description: The Prism Front-Surface Beam Sampler (PFSA) is a C-mount fixture housing a UV-Grade Fused Silica right angle prism, used for sampling the front surface reflection for high power/energy beam-profiling applications. Reflection at nominal incidence of 45°is polarization and wavelength dependent, with 532nm s-polarization reflected at 8.27%, and p-polarization at 0.68%. Specification Recommended Wavelengths: 200nm to ~2500nm Interface: C-mount Damage Threshold: CW> 100MW/cm2 Reflection: P: 0.64-0.88% , S: 8.01-9.40% Material: UV-Grade Fused Silica Clear Aperture: 14mmx14mm
