Universal fit 37mm CPL filter especially for dashcams and other cameras. This CPL filter prevents annoying and harmful reflections in the image of, for example, the dashboard of your car. The filter serves as a kind of Polaroid sunglasses for the lens. Especially in sunny conditions, a CPL filter can significantly improve image quality.

This filter consists of two parts: the holder and the filter itself. You stick the holder around the lens with the included thin double-sided tape and you simply screw the filter onto the holder. This makes it easy to install and remove the filter.

Note: The opening for the lens on the holder is 20mm and around this is a circular double-sided tape of +/- 5mm wide (see photo 2). To place the filter over the lens, there should be sufficient surface area around the lens for this.
