Autorefractor
Tomey TR-4000
The Autorefractor Tomey TR-4000 provides highly accurate
measurement of patients’ refractive error. This measurement is obtained
simply by pushing a button. Patient alignment is simple and effortless
with the joystick controller. The Autorefractor Tomey TR-4000 automatically
calculates interpupillary distance (PD) based upon the patient’s
alignment.
Fast
and accurate measurement
With dual CCD cameras for accurate, reliable and repeatable measurements,
the TR-4000 offers a fast (0.3 seconds) measurement time and a unique
multi-averaging system for accurate Refraction readings.
Data output
Refraction results are immediately available on the screen and may be
printed using the system's quiet built-in, high-speed printer. Results
can also be transferred to the office database via the integral RS-232C
connection.
Power saving features
The stand-by, or sleep, mode is automatically activated after five or
ten minutes (operator selected) of idle time. This reduces power consumption,
resulting in operating cost savings, and increases the overall lifetime
of the TR-4000. Simply push the joystick button to reactivate the unit.
