Select an Optical Filter to Suit Changing Conditions

Article Featured in Industrial Photonics

Optical filters have long been critical components in traditional machine vision applications. They maximize contrast, improve color and subject recognition, or otherwise control light reflected from an object under inspection. Typically, filters are used for machine vision tasks that do not vary much from product to product or from one subject to the next. However, recent advances in sensors, artificial intelligence, human-robot interaction and other technologies have led to the use of machine vision in more flexible applications such as sorting, material handling and automated assembly. When choosing a filter for these applications, consider the following.

New Acrylic Longpass Filters

MidOpt introduces new acrylic longpass filters, featured in Imaging Machine Vision Europe

Midwest Optical Systems has introduced new acrylic longpass filters. Acrylic Longpass Filters are frequently used as enclosure windows, to shield lenses and lighting from damage, or to economically control the wavelength emission in large area, broad spectrum light sources.  Because of their durability, they are also commonly used in Food & Drug Administration (FDA) and European Food Safety Authority (EFSA) regulated applications where exposed glass over the inspection area is not permitted. AC370 and AC380 offer anti-abrasion, anti-reflection coatings which can also withstand harsh solvents such as acetone and MEK.
