The Prisma AF portable video magnifier introduces a new level of simplicity and ease of use, with the integration of full auto focus technology to the Prisma product. Now you can enjoy a broad range of magnification levels (up to 34x on a 32’’ screen) and a premium image quality with the touch of a button. Simple to connect & intuitive to use, its discrete, light weight design (less than 1.3kg) means it can be easily moved or located in a position to best suit your needs. The advanced image processing from Ash enhances the image quality to deliver a well-defined magnified image in a variety of modes. The adjustable LED lighting also serves to enhance the viewing of an object. Having premium image quality decreases your eye fatigue allowing you to read more quickly and for longer periods of time.
