Product Details
Tilting 7" TFT LCD Screen: The screen angle can be adjusted from 0 to 85 degrees. The large touch screen displays icons and menus clearly for easy navigation.
Equipped with Keratometer: You can select from three measurement modes via the screen keys: REF, KER, and R&K. This feature allows for both eye diopter and corneal curvature measurement.
High precision: Using rotating prism and a double telecentric optical system, along with the follow-up colorful fogging chart system, this machine delivers exceptional accuracy and reliability.
Built-In Thermal Printer: The printed results are clear and precise. Data for the left and right eye can be recorded separately up to 10 times. The printer paper is easily replaceable.
Measurement Methods : The system can be set to manual or automatic measurements using the screen keys. A tracking mode automatically adjusts the measurement focus via automatic sensing and a 3D mobile device.
Simple and Convenient Operation : Control the machine easily with the touch screen, or use the shortcut keys and joystick to move the machine forward/backward, left/right, or up/down.
