Serie IF is an uncoated window substrate, polished on two sides, with a wedge of 30±5 arc minutes. Therefore, they form the foundation for several coated products, such as, W1, W2, beamsplitters, output couplers, harmonic separators, dichroic mirrors, and partial reflectors.
  • Substrate material: Suprasil 1, UV grade fused silica or BK7
  • Wedge tolerance: 30 ±5 minutes
  • Diameter φ+0/-0.25 mm
  • Reflected beams from both surfaces separately usable
  • Output coupler, beamsplitter, or beam-sampling substrate
  • λ/10 transmitted wavefront, 10-5 surface quality
