6.7 Measurement of Ultraviolet (UV) Transmission
Checks the UV protection function by taking a measurement of the UV transmission of lens.
The light wavelength for UV transmittance measurement is 375 nm. This does not measure the transmittance
of a whole area of UV light.
6.7.1 Device Setting
Confirm that “UV Measure” is set as “On” before the measurement of UV transmission.
※ In case of setting “UV Measure” as “Off”, neither UV transmission nor UV transmission
display area is displayed.
If displaying UV transmission graph, set “UV Graph” as “On”.
※ The graph is displayed only in the progressive lens measurement mode.
(Refer to 4.2.1. Device Setting.)
6.7.2 Measurement of UV Transmission after Measuring Degree
The UV transmission measurement is performed after achieving an alignment of the lens and
pressing the “Memory/Add switch” to store the measurement values.
In case of taking a measurement again, clear the measurement values first by touching
.
※The values are cleared in order of degree of lens and UV transmission.
At the time of progressive lens measurement, the UV transmission measurement is
performed after taking a measurement of far point
.
