ESV3000 ETDRS Standardized Viewer
ETDRS Standardize Acuity Illuminated Cabinet ESV3000 contains patented internal calibration technology which automatically controls the standardized LEDs (light emitting diodes) output. When this lighting technology is combined with a universal standard power supply, the result is consistent standardized lighting that makes the ESV3000 the most accurate, easy to use tester for evaluating ETDRS and LogMAR acuity. Simply turn on the device and with a push of a button, the ESV3000 automatically calibrates to a photopic light level of 85 cd/m2 , or a mesopic level of 3 cd/m2. These light levels are recommended by the National Academy of Sciences' Committee for Vision Testing Standards and are required by the FDA for ETDRS evaluation in clinical trials.
    ETDRS Standardized acuity testing is now a reality with photopic 85 cd/m2 or mesopic light levels 3 cd/m2
    ESV3000 is low maintenance with no bulbs to warm up, burn in or replace.
