RK-F2 Tam Otomatik Otorefkeratometre

*New Product!


  • Selectable Measurement Modes 
    The three-dimensional tracking system of the RK-F2 features a wide range of movement, so that the examinee's pupil can be detected easily. When in Full Auto mode, the unit is a one touch operation for auto-refraction and curvature measurement in both eyes. Just press the start button and the ref-keratometer automatically aligns and measures both eyes. For added flexibility, Auto and Manual measurement modes are included.
  • Small Pupil Size 
    At 2 mm, the small pupil mode helps contribute to an efficient screening and is useful when a patient's pupils are difficult to dilate. The short reaching distance between the patient and operator allows closer personal interaction and easy access to the patient's eyes.
  • Retro-Illumination 
    Using infrared retro-illumination, the RK-F2 provides a detailed view of the eye which is helpful for identifying cataracts, vitreous opacity, scars, and other serious eye problems.
  • Corneal Periphery Measurement 
    The peripheral keratometry mode provides accurate measurements for examining oblique astigmatisms and helps determine the best fit for a contact lens. The RK-F2 can be used to make a series of measurements at a 30 degree angle from the eye's center along the attentive meridians.
  • Wide Measurement Range 
    The dioptric measurement range of -30D to +22D allows examination of strong myopia or hyperopia. The astigmatic measurement range extends from 0 to 10D. The radius of curvature extends from 5 to 10 mm (33.75D to 67.5D) for keratometry.
  • Compact and Lightweight 
    The compact design of the RK-F2 is designed to be operated either sitting or standing, whichever is more comfortable for the operator. Weighing a little more than 33 pounds, the lightweight RK-F2 maximizes small work areas and comfortably fits on a Canon instrument table (sold separately) with a Canon Full Auto Tonometer or Canon Non-Mydriatic Retinal Camera (both sold separately). Keeping the Canon machines next to one another can help expedite the exam process.
  • Multi-Functional Color LCD Monitor 
    The 5.7 inch color LCD monitor tilts 40° making the RK-F2 easy to use if the operator is sitting or standing. The clear LCD display also includes multi-functional screen buttons allowing the operator to switch menus as needed.
  • Motorized Omni-Directional Joystick 
    Aligning the patient's eye is easy using the motorized omni-directional joystick with a fine focus dial. All positioning may be performed with one hand allowing the other hand to work with the patient, if needed. The top of the joystick button has the start button which can immediately be pressed once the patient is properly positioned.
  • Built-In Printer 
    The front-loaded, high speed built-in printer includes an auto cutter making it simple to remove the print-out. The ECO setting reduces the printing density and thereby conserves the paper necessary for printing by up to 50% as compared to printing without using the ECO setting. New paper rolls can easily be inserted through the feeder.
