Machine vision is a technology that enables automated devices to "see." Machine vision systems combine optics and mechanics to create tools that can adjust optics in real-time to perform inspections and aid robotic systems. In our increasingly automated world, machine vision has become an essential component in manufacturing, farming, robotics, and many other areas. Quality optical components are critical to the function of machine vision systems. Optical systems for machine vision may involve high quality fixed focal length lenses, telecentric, or adjustable lens systems (zoom or liquid lenses).

Ball lenses are highly transparent spheres made with optical glass. Some of the earliest microscope lenses — developed by Antoni van Leeuwenhoek — relied on surface tension to form small spheres from melted glass. These lenses achieved magnifications as large as 275x and were as small as 1.5 mm in diameter.1 However, since ball lenses can cause spherical aberrations and typically have to be apertured to exclude non-paraxial rays when used for imaging, they are often replaced with different geometries, such as aspheric lenses, in microscopes today. Modern technologies involve using ball lenses to couple light between optical fibers or to focus light from a diode laser into a fiber optic. Ball lenses are commonly used in barcode scanning, optical sensing, and endoscopy.

In the fast-moving industry of optics, there are often problems that arise and need to be dealt with immediately in order to keep production running smoothly and on schedule. Whether they occur in the design, manufacturing, or assembly stage, problems can prove to be catastrophic if not handled properly. Below, we touch upon a few real issues in all three of these stages of optics and give some advice on how to keep your operation running efficiently.

When creating an optical system, there are many challenges an engineer faces when choosing how to design a lens. Choosing the correct lens without the right tools can prove to be very difficult and costly. Zemax, a ray-tracing optical design software program, provides designs and analyses for imaging and illumination systems. This allows for the user to view the way different lenses work while providing analysis diagrams documenting a variety of data sets. Zemax is a great tool to improve performance, shorten time to market, and reduce production costs.
