What is it?

  • Lockable fine-focus
    Fine-adjustable focus on each ocular means that you can focus with each eye, then lock the ocular in place with a tiny screw. This allows you to achieve a perfectly focused image, at your working distance.
  • Power-Up system
    ExamVision’s unique Power-Up system means the magnification of Kepler Kompakt can be changed quickly by ExamVision – so if you want to increase or change your magnification at a later date, you can do so without investing in a whole new loupe.
  • HD
    Stands for High Definition and refers to the unique ExamVision multi lens system, which gives optimal depth of field and true colour transmission.
  • System TTL
    The TTL (Through the Lens) system reduces the distance between the eye and the loupe. The Galilean telescope system is mounted through the lens, ensuring a wide field of view with high definition.
  • Prisma Lens System™
    ExamVision loupes can contain a prism, which refracts the image, allowing a more relaxed working position to reduce stress and pain in the neck and back. This can help to achieve a better ergonomic working posture.
  • Galilean telescope
    The Galilean telescope consists of a convex objective lense and a concave ocular lense which give realistic images the correct way around. It is highly compact and lightweight, reducing strain during daily use of your loupes.
  • Super Hi-Vision
    An extra coating, giving more than twice the scratch resistance of the leading anti-reflection coating, plus maximum anti-reflection and superior smudge resistance. Ask your ExamVision dealer about the benefits of Super Hi-Vision on your loupes.
  • Field of View
    The field of view is no greater than the width of the image. The larger the magnification the smaller the field of view.

    ExamVision loupes are mounted through the lens (TTL) so that the field of view is larger, giving a sharper and more defined image.

  • Depth of Field
    The distance in which an object is entirely defined in a telescope system. In a higher quality optical system, the depth of field is higher.

    The magnification affects the depth of field. The stronger the magnification, the lower the depth of field, requiring a static posture to maintain the focus.

  • LED illumination

    A light emitting diode, more commonly known as an LED which emits cold white light.

    Advantages of LEDS

    - Brightness: LEDS are brighter than normal bulbs and concentrate light on a single point rather than diffusing.
    -Lifespan: An Led can last for 50,000 hours or six years constant use.

  • Bundled light source system
    ExamVision provides the LED Focus Optic Illuminator lamp with the Bundled Light Source system technology. Specially developed by ExamVision, the system creates an highly concentrated beam and prevents polymerisation of dental composites.
  • Hi-Index glass
    Hi-Index glass is able to bend light more effectively than ordinary glass, so lenses can be lighter and thinner. This is especially important if you have prescription in your carrier lenses. ExamVision uses Hi-index glass as standard.
  • Multi-layer glass
    Highest quality glass, with multiple coatings to make the glass less reflective, and more resilient to scratching. ExamVision uses multi-layer glass as standard, with hard coat and anti-reflective properties. Super hi-vision is an optional extra.
