    AI Overview
    Plano-Concave Lenses - Avantier Inc.
    Plano-concave lenses (circular or rectangular) are optical components with one flat and one concave surface, designed for negative focal lengths, diverging light beams, and reducing image size. They are ideal for laser beam expansion,, projection, and image reduction. Common materials include UVFS, BK7, and CaF2, with coatings for UV to IR. 
    Key Types and Applications 
    • Circular Plano-Concave Lenses: Typically used for, beam expansion, light projection, and in optical systems needing a negative focal length.
    • Rectangular Plano-Concave Lenses (Cylindrical): Used for uni-axial negative imaging, laser line generation, and anamorphic beam shaping, effectively reducing the aspect ratio of images. 
    Specifications and Materials 
    • Materials: Optical Glass, Fused Silica (UVFS), BK7, CaF2, or Plastics.
    • Coatings: Anti-reflection (AR) coatings (e.g., VIS-EXT, MgF2, NIR) to improve transmission.
    • Dimensions: Available in, small sizes (mm scale) for laser systems to larger diameters up to 500mm.
    • Tolerances: High-precision, options include tolerances of $\pm$0.01mm for diameter and thickness. 
    Main Functions 
    • Beam Divergence: Spreads collimated light.
    • Image Reduction: Minimizes image size.
    • Anamorphic Beam Expansion: Expands light in only one dimension.
    • Laser Line Generation: Used in laser systems to change beam aspects. 
    These lenses are essential in laser applications, medical imaging, and optical instrumentation for manipulating light paths.
