The GR-10N has a fixed diffuser, so a filter cannot be attached directly as is.
In that case, one option is to purchase commercially available sheet-type polarizing film and apply it.
Polarizing film with a suitable level of rigidity, which can be cut with scissors, is convenient.
Cut it into a donut shape and attach it to the ring light using double-sided tape or similar adhesive.
(The following is not actual polarizing film, but an illustration of the process.)
Of course, it is necessary to place a polarizing filter not only on the light-emitting side but also on the light-receiving side.
For this, existing filters can be repurposed.
A polarizing filter is also placed on the light-receiving side.
