HD 10X Magnification - Maximizing sharpness was one of the biggest priorities when building this device, the first class optics ensure excellent edge to edge magnification free 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 cross-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 easy on 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 charged by USB-C cable. Like a scalpel, the dermatoscope is an awesome inst ent in trained hands. It's also a great tool for self-diagnostics with the help of dermatologist or dermascope App. Bright LED illumination Polarized and non-polarized lighting Contact and non-contact imaging 10x Magnification Full frame display on phone Universal lens clip; available for all phone & tablet Easy to handle and focus Lithium ion battery & USB-C charge Automatic shut down High quality but affordable Optical Design:All glass, 4 elements, 4 groups Magnification:10X Distortion:2% Resolution:300 LP/MM (Axis) 250 LP/MM (Edges) Polarization:90° Cross Polarized LED Type:SMD LED beads Battery Capacity:200mAh L
