Midwest Optical Systems, Inc.

Machine vision filters are used to increase the contrast of the subject a camera is viewing, improving its ability to distinguish desired characteristics.This allows for increased accuracy and speed. Filters are selected by matching a filter type to the lighting being used and a filter size to the diameter of the camera lens.

Midwest specifically designs and manufactures filters for use with monochromatic or white LED lighting, fiber optic illumination, structured diode-generated light patterns, and other lighting commonly used in machine vision applications. When matched together with the correct lighting, filtering is one of the most important factors that controls the ability of an optical system to produce acceptable results.

Midwest carries in-stock a wide variety of filter options designed to securely and quickly mount to the smaller diameter lenses used with CCD and CMOS cameras. Unlike most other filters that are sold as being for use with machine vision, not only are Midwest Optical's filters truly off-the-shelf and ready-to-use, but the filter material is also sized for each mount so that there is no restriction to the field of view.
