No. 455:
Digital display in 0.5 mm steps. It is easy to understand and accurate at a glance.
Features:
- No need to replace the lamp with an LED light source, realizing battery life of 3 to 4 times compared to the conventional one.
- By adopting a linear sensor, it became a smoother lever operation.
- Measurement method is "cornea reflected light matching method" that aligns the light spot on the pupil with the measurement line.
- The measured value is digitally displayed with three values of R · R + L · L.
- Since the display is 0.5 mm pitch, more accurate measurement value can be obtained.
- It is also possible to switch between binocular measurement and one eye measurement.
- It is possible to measure P. D. of gaze point distance from 30 cm to infinity.
- In order to prevent power consumption due to forgetting to switch off, it has a function that automatically switches off in 1 minute after completion of operation. (TOWA)
- Distance from corneal vertex to lens or frame can be measured.
