Are you wondering if a polarizer can improve the image quality of your dash cam? What even is a CPL filter?
With the BlackVue Dash Cam CPL Filter (BF-1) for DR750X and DR900X now available, we thought it is a good time to discuss the topic of circular polarizing lenses. What they are good for, how to use them properly and when to avoid them.
The exact meaning of the acronym may vary from source to source. Sometimes it stands for circular polarizing lens, and sometimes you might also see reference to circular polarizer/linear. For all intents and purposes, they refer to the same thing.
In the case of the BlackVue CPL Filter, CPL stands for Circular Polarizing Lens. It is simply a type of polarizer. Oh, and “circular” has nothing to do with the shape of the filter, in case you were wondering. Instead, it has to do with the way the filter polarizes the light. The other type is “linear”.
Features:
- Adjustable Circular Polarizer/Linear (CPL) Filter for BlackVue Dashcams.
- Reduces reflections in daylight. Not recommended for night or low-light recording.
- Compatibility: DR900X, DR750X front cameras and past models with similar form factors (DR900S, DR750S, DR650S, DR650GW).
