Photopolymers in the form of photoresist are extensively used in the fabrication of printed circuitry. In order to fabricate circuitry with fine lines one must maintain tight control on the characteristics of the photoresist used. Shown above is an inexpensive tool for quickly and efficiently obtaining a figure of merit for a photoresist.
