The 400x microscope lens is great for extreme close-ups of skin, leaf, jewelry, and other objects with fine detail. Different from traditional macro photography, this lens has a led light inside and can work close to the subject to capture rich textures, materials, and living things that our phones (and eyes!) were never before capable of seeing.LED light illumination400x Magnification Universal lens clip; available for all phoneEasy to handle and focusLithium ion battery & USB-C chargeMagnification: 400XDistortion: 10%Resolution : 300 LP/MM (Axis) 200 LP/MM (Edges)Compatible : 98% SmartphoneLED Type : SMD LED beadsBattery Capacity : 300mAh Lithium ionCharge : USB-CColour:blackMaterial:plasticPackage Contents:1 x Digital MicroscopeOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
