Features


  • Non-Polarizing Plate Beamsplitters: Designed to divide an incident, monochromatic beam into reflected and transmitted components while maintaining the polarization characteristics of the incident beam.

  • High-Quality Coatings: One side is coated with a dielectric, non-polarizing, partial reflection coating, and the reverse side features a high-efficiency, narrowband, anti-reflection coating.

  • Standard Materials: Available in BK7, UVFS, and ZnSe materials.

  • Angle of Incidence: Optimized for 45º angle of incidence.

  • Surface Figure: Achieves λ/20 at 632 nm for BK7 and UVFS, and λ/40 at 10.6 µm for ZnSe.

  • Surface Quality: 10-5 for BK7 and UVFS, 40-20 for ZnSe, ensuring high precision.

  • Diameter Tolerance: Precisely manufactured with a tolerance of +0.000", –0.010".

  • Thickness Tolerance: Maintained within ±0.010".

  • Wedge: ≤ 3 arc minutes for minimized beam deviation.

  • Bevels: 0.010" – 0.030" at 45º for edge protection.

  • Clear Aperture: Central 85% of the diameter is clear, ensuring optimal use.

  • Reflectance: Adjustable between 10% and 90% ± 3% with |R – Rs.p| ≤ 3%.

  • Anti-Reflection Coating: Provides unpolarized reflectance ≤ 0.5% at 45º.
