Baader T-2 bent mirror (Zeiss) Prism with BBHS\u00ae coating<\/h2>\n

Visit Baader T-2 Stardiagonal Prism<\/strong> is a top-of-the-range angled gearbox designed according to Zeiss optical standards<\/strong>. Equipped with glass prism BaK4<\/strong> and the famous BBHS\u00ae<\/strong>, It offers exceptional light transmission and maximum contrast, ideal for lunar, planetary and solar observation.<\/p>\n

\n

High-precision prism conforming to Zeiss standards<\/h3>\n

The prism is manufactured to Zeiss specifications to guarantee extremely high optical precision.<\/p>\n

    \n
  • High-quality BaK4 prism<\/li>\n
  • Manufactured to Zeiss standards<\/li>\n
  • Multi-treated optical surfaces<\/li>\n
  • Flatness and precision approx. 5 times higher<\/strong> to standard prisms<\/li>\n<\/ul>\n

    This precision results in a particularly sharp image, with high contrast and excellent reproduction of fine details.<\/p>\n

    \n

    High-performance BBHS\u00ae treatment<\/h3>\n

    The treatment BBHS\u00ae (Broad Band Hard Silver)<\/strong> ensures maximum light transmission and durability.<\/p>\n

      \n
    • Very high light transmission<\/li>\n
    • Optimum contrast<\/li>\n
    • Durable, resistant treatment<\/li>\n
    • Ideal performance for planetary and lunar observation<\/li>\n<\/ul>\n
      \n

      Compact T-2 modular design<\/h3>\n

      Thanks to T-2 threads on both sides<\/strong>, This angled lens can be easily integrated into a wide range of optical systems, while keeping optical length to a minimum.<\/p>\n

        \n
      • T-2 connection on both sides<\/li>\n
      • Extremely compact design<\/li>\n
      • Highly flexible integration into an optical train<\/li>\n
      • Adaptable to different types of telescopes<\/li>\n<\/ul>\n
        \n

        Large clear opening<\/h3>\n
          \n
        • Clear opening: 35 mm<\/strong><\/li>\n
        • Telescope connection : 2\u2033 or 1.25\u2033<\/strong> (depending on adapter)<\/li>\n
        • Eyepiece connection : 1,25\u2033<\/strong><\/li>\n<\/ul>\n

          This generous aperture limits vignetting and preserves the full brightness of the optical system.<\/p>\n

          \n

          Robust mechanical construction<\/h3>\n

          The prism is mounted in a precision-machined metal housing<\/strong>, This is far superior to the plastic housings often used on standard prisms.<\/p>\n

            \n
          • All-metal housing<\/li>\n
          • High mechanical rigidity<\/li>\n
          • Precise, long-lasting optical support<\/li>\n
          • Premium manufacturing quality<\/li>\n<\/ul>\n
