HD 10X Magnification - Maximizing sharpness was one of the biggest priorities when building this device, the first class optics excellent edge magnification from spherical and chromatic aberration.Polarized & Non Polarized Light - Polarized dermatoscopes, like non-polarized dermatoscopes, contain light-emitting diodes to provide illumination and are equipped with a magnification lens. However, polarized dermatoscope use two polarized filters to achieve -polarization. Hence, it does not require direct contact with the skin, and do not require the use of immersion liquids.The DE-400 dermatoscope can be switched to both polarized and non polarized light model, available in different lesion diagnose situation.Phone & Tablet Compatibility - The universal lens clip attachment gives the ability to attach dermatoscope on smartphone or tablet and take pictures, so the lesions can be captured and scrutinized.Best part? It compatible with all phone in the market, with a universal lens clip or a and off phone cover.Charging - With built in 200mAh Lithium ion battery, the dermatoscope can constantly working at least 90 minutes, and it can be by USB-C cable.Like a scalpel, the dermatoscope is an awesome instrument in trained hands. It's also a great tool for self-diagnostics with the help of dermatologist or dermascope App.Bright LED illuminationPolarized and non-polarized lightingContact and non-contact imaging10x MagnificationFull frame display on phoneUniversal lens clip; available for all phone & tabletEasy to handle and focusLithium ion battery & USB-C chargeAutomatic shut down but affordableOptical Design:All glass, 4 elements, 4 groupsMagnification:10XDistortion:2%Resolution:300 LP/MM (Axis) 250 LP/MM (Ed)Polarization:90 PolarizedLED Type:SMD LED beadsBattery Capacity:200mAh Lithium ionCharge:USB-CColour:BlackMaterial:PlasticPackage Contents:1 * Portable Dermatoscope Kit
