OVERVIEW
Wide View Window Avoids "Instruments Myopia"
Use of Wide View Window allows subject to relax during measurement, as looking into the window naturally with both eyes can minimize instrument myopia.
No Auto Fogging Means "No Accomodation"
Measurement princple without autofogging function prevents subjects e.g., children from using accomodating.
Near Vision Reading
Near reading tests can be performed with attached near reading card of standard accessories.
Clear 5.6 inch color monitor
Built-in clear 5.6 inch color monitor that produces superb colorful display of the icons for easier identification to select your desired choices for measurement.
Data Screen Function
Measured data can be seen on the monitor without printing out.
SE Value Display Function (spherical equivalent values)
You can check accomodation of the measured eye with SE values.
Quick Printer with Automatic Cutter
Printing paper is automatically cut when it is released.
Auto Start Function
Starts measuring automatically when alignment meets measurement requirements.
IOL Measurement Function Installed
You can measure the IOL (Intraocular lens) implanted eye.
Miniumum Pupil Diameter : 2.3 mm
Allows you to measure much smaller pupils that conventional units.
RS-232C Setting Function
You can send the measurement data to an external computer through an interface.
Output Terminal
This terminal outputs an NTSC video terminal. If you connect an external monitor, you can observe the same image that appears on the internal monitor screen of Nvision-K 5001 simultaneuously.
