Another important component of a successful machine vision system is choosing the appropriate filter. The right filter can dramatically improve the work efficiency of a vision system. Filters are used to increase contrast, separate color or control camera exposure. When increased contrast is achieved, a system has greater accuracy and can sometimes operate at an increased speed. Filters also help to protect the lenses behind them. FSI Technologies Inc. can offer a wide variety of filters to meet the needs of many different types of applications. Filter types include “bandpass filters”, “polarizing filters”, “longpass filters” and “neutral density” filters.
