AR400 ringflash polarizer


product information

Used by the professional industry. In use by many VFX studios worldwide.

If you want fully crosspolarized shots for photgrammetry, photometry of even just for photography to block out all specular light of your ringflash and get correct color data, this polarizing filter is the best choice for your scanning device.

It's a pecise, sturdy and smooth 3D printed frame together with a high quality linear polarizing film.
The light 125 grams of the filter doesn't add too much weight to your rig. It's attachable through magnets directly to the ringflash and stays stable in every situation. Thanks to its magnets and the handle it is adjustable in 45 degrees steps to easily change from cross-polarized to parallel-polarized within seconds. It stays cool even on long scanning trips because of its ventilation holes on the side.

It's compatible for the Godox Witstro AR 400, Quadralite RX400, Flashpoint RF-400 and RIKO400 and Walimex Pro HS-400.

Contact us and we can figure out together if we can help you. We plan to offer single replacement parts to purchase in the future.

Simply put the filter on your ringflash and a polarisation filter on your lens. Turn on the LEDs of the ringflash and point it to a mirror or another reflective surface. Rotate the filter on your lens until the reflection of the LEDs in the mirror are no visible for the camera anymore. It’s not possible to completely get rid of the reflections but almost. The only visible light is dark blue/purple on metallic objects. Now your light and your camera are crosspolarized. If you turn the filter on the light by 90 degrees, it’s parallel polarized. 180 degrees is cross polarized again. If you have any issues, don’t hesitate to contact us.

I normally build my Photogrammetry Gear by myself.

But I was always curious about how a premade Polarizer would perform,

I can report: This Filter is working really well. The Quality of both the 3d printed Frame and the Film inside the Polarizer is great.

I would totally order that Polarizer again.


Great and strong filter!

I had another filter that was losing it’s magnets over time and was very heavy. I’m glad I got this one, it’s really an upgrade and worth the money!
