    AI Overview
    Rhomboid Prism, Reflective Prism, ios Optics
    Coated Rhomboid Prisms are optical components that shift a light beam laterally without changing its direction or inverting the image, featuring special thin-film coatings (like Anti-Reflection or specialized beam splitters) on their surfaces for specific spectral performance, used extensively in lasers, imaging, surveying, and military systems to precisely steer light and adjust optical paths. These prisms typically use N-BK7 glass or fused silica and offer high precision with tight angle/surface tolerances, often with broadband AR coatings for enhanced transmission in visible or infrared ranges. 
    Key Features & Functionality: 
    • Lateral Displacement: Moves a beam parallel to itself, equal to the prism's length (D).
    • No Image Inversion: Maintains image orientation, crucial for imaging systems like microscopes.
    • Coatings: Anti-Reflection (AR) coatings for high transmission, or specialized dielectric coatings for beam splitting/polarization.
    • Materials: Common substrates include N-BK7 glass and UV Fused Silica; Germanium for IR applications.
    • Applications: Laser beam steering, microscopy (separating signal/excitation light), surveying, military optics (periscopes), and industrial endoscopes. 
    Types of Coatings: 
    • BBAR (Broadband Anti-Reflection): Reduces reflections, ensuring high light throughput (e.g., Ravg ≤0.4% in VIS range).
    • IR Coatings: For infrared applications, made from materials like Germanium.
    • Custom Coatings: For specific wavelengths or polarization requirements (e.g., polarizing beam splitters). 
    Specifications to Look For: 
    • Beam Deviation: How much the output angle differs from the input (e.g., ±30 arcseconds).
    • Surface Quality: Scratch-dig rating (e.g., 40-20).
    • Surface Flatness/Irregularity: Precision of the optical surfaces (e.g., λ/2 or better).
    • Angle Tolerance: Accuracy of prism angles (e.g., ±5 arcseconds).
