4-16 TEST PARAMETERS AND STRATEGIES
REV.B 02/03 PN 51680-1 HUMPHREY FIELD ANALYZER II - i series
In addition to the standard white stimulus, all central field tests may be performed using a blue
or red stimulus on a white background. The filters to create the colored stimuli are listed and
characterized below.
Color Filter
Blue 440 nm Blue (model 745i, 750i)
OCLI Dichroic Blue (model 740i)
Red Hoya R62
Note: This is not the same as Blue-Yellow Testing. See previous discussion for details.
Note: STATPAC analysis is not available for tests using either the red or blue stimulus.
1. From the start test screen, select CHANGE PARAMETERS.
2. Open the stimulus color drop-down menu and choose either BLUE or RED.
3. Proceed as you would for any white stimulus test.
Note: The decibel to apostilb comparison chart in the Appendix is different in color testing
than it is in white testing. In color testing, zero decibels still represents the maximum
instrument brightness although that maximum brightness is less than 10,000 asb. Decibel
values are still valid for comparison of relative brightness for a given color filter.
