This linear polarizing filter gives your OpenMV Cam the ability to see in environments with intense sunlight. You absolutely need a linear polarizing filter if you plan on doing any application that involves pointing the OpenMV Cam down at something that could be lit by sunlight.

We get these polarizing filters custom made for us to fit inside your OpenMV Cam's M12 lens mount from Edmund's Optics. This is why they are a little pricey. But, they are defiantly worth it.

Filter Performance


Mount the polarizing filter inside of your OpenMV Cam's lens mount (also, make sure to take the protective film off the front and back of the polarizing filter). Depending on the orientation you mount the polarizing filter it will filter out horizontally or vertically polarized light. You most likely will need to test the filter with your OpenMV Cam twice to get the orientation right. Alternatively, you can hold the filter up to the flat surface that's reflecting light and try to see if the glare goes away by rotating the filter.
