The MacuScope’s™ technology is superior to devices that use LED’s as test light sources. The MacuScope™ employs a narrow band interference filter that defines a specific test wavelength so that no correction factor is necessary. LED’s are broadband width, and measure some type of non specific optical density over the LED’s wide wavelength range. This greatly decreases the accuracy. Also, the lower luminance produced with an LED light source compromises the integrity of the test.
