21 Apr 2010 Thin Film Polarizers (TFP's) is used to split a laser beam into two parts with S and P Polarizations. Our Laser Thin Film Polarizers (TFP) are coated to separate orthogonal polarizations with a high extinction ratio. They are designed for both Nd:Laser line (1053nm, 1064nm, 527nm, 532nm) and over a broad spectral bandwidth centered on 800 nm (best for Ti: Sapphire Ultrafast Amplifiers). TFP is intended to be used at Brewster's angle, and angle tuning is required to optimize reflection and transmission performance.
