Good-Lite ESV3000 ETDRS Kit with Original Series 13ft/4m ETDRS Charts
The ESV3000 ETDRS Illuminated Cabinet features patented international calibration technology which automatically controls the standardized LEDs output. This unit was specifically created for the rigorous lighting standards needed for clinical trials and vision research. When this lighting technology is combined with a universal standard power supply, the output is a consistent standardized lighting that makes the ESV3000 the most accurate, easy to use tester evaluating ETDRS and LogMAR acuity during research. All you have to do is turn on the unit 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. As opposed to previous illuminator cabinets which use outdated fluorescent bulbs, there is no warm up period and no requirement to replace the light source. The old fluorescent light bulbs have to be replaced every 2,000 hours, or once a year, and new bulbs have to be "burned in" before use. For the ESV3000, the LEDs last up to 20+ years of normal use, never need replacement and require no burn-in period. Just plug it in and it is ready to test. For use outside the US, this unit has a universal power supply that is easily adapted to 100V to 240V, unlike cabinets that use fluorescent bulbs, which require the use of 110V input voltage.
