Sorry. What is a Shepard knock down ceiling?

Hi Ruth,

Thanks for the question. Here is a resource from a company that is one of the leaders in the production of machine vision cameras and software:

There is a lot of related material and examples of applications. I hope this is helpful.

Thanks,

As Brian @ I4 Solutions has mentioned, adding a band-pass filter with the camera to make the wavelength of the light out is the most cost effective solution.

Hello Michael,

I am with Metaphase Lighting. For Israel, our distributor 1vision would be a great partner to work with. They are very experienced with all aspects of a successful machine vision system. Everything from cameras, software, contacts with integrators, and the most important part, lighting :).

Jana, for the illumination part of this application, its key to have good diffused lighting. When looking at the grains, you tend to identify the grains by contrast in colors. Your going to need an illumination system that helps produce good color rendering. On deployed systems that sound very similar to your application, we have use 2 different diffused light sources.

For Area Scan, a dome light would be best to give you accurate colors. Since you are looking at wood, that tends to be more rectangular rather then circular, our elongated dome (Diffused Tube) would work best.

If you were to go the line scan route, we offer the same type of solution in a high power compact form factor. This works great for the more narrow field of view with a line scan camera. https://www.metaphase-tech.com/line_lights_line_scan/compact_diffused_tube_line_light/high_power_compact_diffused_tube_line_light
