The 10Q20UF.HB1 Ultrafast Harmonic Beamsplitter is 1.0 in. (25.4 mm) in diameter with high reflectivity at 400 nm, and high transmission at 800 nm. Our harmonic beam splitters are designed to separate Ti:Sapphire laser first order harmonic after frequency multiplication. These 25.4 mm diameter optics with a 3 mm thickness are precision polished select grade fused silica coated with hard refractory multilayers for high damage threshold. Harmonic beamsplitters are sometimes called Dichroic Filters or Beam Combiners.
