The 4th-generation DermLite dermatoscope has been designed from the ground up to be more refined in every detail. An amazingly smooth, ergonomically optimized all-aluminum design that comfortably molds to your hand, DermLite DL4 puts phenomenal versatility, the largest optics of any pocket-size DermLite, and instant on/off control right at your fingertips. Built upon the DL3’s proven polarized & non-polarized lighting and solid battery life, DL4 now offers two brightness levels, a larger field of view, enhanced imaging of deeper pigmentation with two levels of color spectrum control (PigmentBoost Plus), and is still more than 25% smaller than the previous generation. This unit has a 10 year warranty. This product is ISO certified.
