Focal length calculator provides lens options for vision systems

Sept. 20, 2016
Goyo North America has launched a web-based lens focal length calculator that enables users to calculate the most effective lens focal length for their vision system, ensuring that aspect ratio of the sensor size equally pairs with the aspect ratio of the object being imaged. 

Goyo North America has launched a web-based lensfocal length calculator that enables users to calculate the most effective lens focal length for their vision system, ensuring that aspect ratio of the sensor size equally pairs with the aspect ratio of the object being imaged.

An object field of view (FOV) that is properly scaled to the sensor FOV aspect ratio ensures that the image sensor will capture the entire image, preventing image clipping, according to Goyo. Based on the sensor size, working distance, and FOV entered by a user, the calculator computes effective focal length while also providing lens options.

"When developing the Focal Length Calculator, our goal was to create a tool that was easier to use and more accurate than others of its kind," said Goyo President Taki Kadobayashi. "By rigorously testing this tool against optical engineering software and field measurements, we believe we achieved our goal of offering a tool that not only helps our internal team members but that also helps all of our customers and distributors alike."
