Long Wave Infra Red (LWIR) cameras have been used for industrial applications to detect infrared light in the 8-14um wavelength region. This infrared light is invisible radiant energy that we experience as heat but can not see. Applications for LWIR cameras continues to expand past industrial applications now entering into medical markets such as …

A 3D Profile sensor (aka camera) relies on 3D Laser Triangulation techniques that have been around for a long time, but until now were expensive. 3D Laser triangulation a decade ago consisted of using separate components in complicated setups using lasers, lighting, optics and algorithms to capture 3D information. Today, this has become simplified into …

This is a question we get asked frequently: “Why should we pay $200 plus for your board level machine vision camera when we can just get a webcam for $69?” A great question and maybe you can, but what ARE the differences? Basically, there are just a few questions you need to answer to see …

While not an exact figure, we would estimate that about half our client’s problems with machine vision camera connections, dropped frames, etc. comes back to a cabling issue. This is especially true for USB and GigE cameras. In most of these cases, the issue is that the user is using a poor/low quality cable that …
