Polarizing beam splitter GCC-4020 series

cubicfor laser applicationspartial reflectance

A polarizing cube beamsplitter consists of a pair of right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When nonpolarized light is normally emerging through two adjacent faces in perpendicular directions and polarized orthogonally to each other.The transmitted beam is p-polarized while the reflected beam is s-polarized. When the linearly polarized light is incident, it is similarly divided into two beams in a ratio depending upon the orientation of the electric field vector of the incident light beam. These polarizing beamsplitters are available for many common laser wavelengths and broadband ranges. •Material: BK7 fine annealed optical glass •Diameter Tolerance: ±0.15mm •Flatness: λ/4 at 632.8nm •Surface Quality: 60-40 scratch-dig •Clear Aperture: >90% dimension •Extinction Ratio: Tp/Ts>1000:1 •Beam Deviation: 0º±3’ (Tp), 90º±5’(Rs) •Incidence angel: 0º~2º
