Beam Tap I & II Dual Surface Reflectors
Beam Tap I & II Dual Surface Reflectors
Beam Tap I & II are dual surface reflectors for equalizing S & P polarization. They provide laser beam attenuation while reducing polarization with broadband and YAG wavelength beam sampling.
- Dual surface reflector for equalizing S & P polarization
- The two planes of reflection are orthogonal
- UVFS or BK7 See All Features

Features
Equalizing S & P Reflected Polarization
Any arbitrary polarization component can be broken into equivalent S & P components. With complimentary sampling surfaces, any given component gets reflected once as the S polarization, and the second time as the P polarization. Thus using 2 surfaces, the total reflected energy for all polarization components is the sum of the S reflectance and the P reflectance. This causes the sampled beam to have S & P components that are identical to the original beam.
