![]() This block is then ground, or generated, by a metal diamond bonded wheel into a near-finished product. ![]() In addition, most high precision prisms tend to be made in low quantities, meaning an automated process would be unnecessary.įirst, a block of glass (known as a "blank") of a specified grade and glass type is obtained. Due to the variability in shape, size, and, most importantly, the number of surfaces, a large-scale automated process for prism manufacturing is quite infeasible. ![]() ![]() In order to be used successfully in most applications, prisms must be manufactured with very strict tolerances and accuracies. PRISM MANUFACTURINGīefore delving into the theory behind prisms, consider their manufacturing process. Therefore, the substitution of one prism in lieu of several mirrors reduces potential alignment errors, increasing accuracy and minimizing the size and complexity of a system. Often, multiple mirrors are needed to achieve results similar to a single prism. Replacing mirror assemblies is perhaps the most useful application of prisms, since they both bend or fold light and change image parity. A notable characteristic of prisms is their ability to be modeled as a system of plane mirrors in order to simulate the reflection of light within the prism medium.
