About This Product
The microscope is moved across or up and down until the crossline sits on each edge of the object, and the difference in vernier readings gives the length. It is used for the diameter of capillary tubes and wires, real and apparent depth to find refractive index, and the diameters of Newton’s rings. Schools, colleges and institutes in Tanzania, New Zealand, Lebanon, Qatar and Serbia can order the Travelling Microscope from Educational Instrument.
