Australia Cottonscope company is a company that designs and manufactures instruments calls Diamscope , This instrument is used to measure the diameters of glass fibers, ceramic fibers, synthetic fibers and carbon fibers,It can be measured up to 20,000 fibers per minute in a water bath and provide an average diameter and a diameter distribution in the range of 0.5 to 50 microns.

Diamscope instrument was developed by its parent company BSC Electronics ,The latter is the world leader in the design and manufacture of fiberglass instruments. It has been operating fiber measuring instruments for more than 20 years and has been used in more than 30 countries.The full name of the OFDA is the “optical fiber-based fiber diameter analyzer”, which uses the latest digital video technology, unmatched in many applications. For example, in measuring the use of fiberglass, the resolution and speed of OFDA makes it the only option for measuring ultra-fine glass fibers for the highest quality circuit boards.
