100X Smartphone Microscope Improved Version

This is a much improved version of the smart phone microscope clip by the PNNL. It makes almost any smart phone camera or tablet camera into a 100X microscope. It requires the use of an inexpensive 3.5 mm glass bead which can be purchased in bulk from various sources on line. Be sure to get the 3.5 mm size for this clip. This version includes slots for small dental rubber bands used for gripping the phone, and to aid in focus.
