    Beam Splitter Penta Prism For Laser Optics Prism-Quarton ...
    High-precision beamsplitter penta prisms combine a standard penta prism with a wedge, using special dielectric coatings to split light (often 50/50) while maintaining stable, alignment-insensitive 90° deviation, crucial for demanding applications like laser guidance or surveying, featuring excellent surface flatness and coatings for UV to NIR ranges. 
    How They Work 
    1. Construction: A precision penta prism (deflects light 90° without inversion) is cemented to a wedge prism.
    2. Coating: An interference (beamsplitter) coating is applied to the cemented interface, allowing some light to pass and some to reflect.
    3. Alignment Stability: The penta prism's geometry ensures that small misalignments don't significantly change the 90° angle, providing stable performance.
    4. Image Preservation: They maintain an erect, unreversed image, unlike some other prism types. 
    Key Features & Benefits 
    • Stable Deviation: Fixed 90° deflection, insensitive to prism rotation (deviation tolerance often <10 arcseconds).
    • High Accuracy: Achieved through superior surface flatness and polishing.
    • Versatile Coatings: Available with anti-reflection (AR) coatings and custom dielectric coatings for specific wavelengths (UV, Visible, NIR).
    • Applications: Laser systems, image erection, surveillance, range-finding. 
    Where to Find Them
    Leading optical component suppliers offer these, often as custom or OEM products, focusing on high quality materials like N-BK7 or Fused Silica, and stringent surface quality (e.g., 60/40 or better) for high-precision needs.
