This is by far the best shield/protection for thermal units.
The honeycomb mesh can stop a BB (airsoft) traveling at more than 400 FPS (tested at point blank), and still having close to no impact on the sensor image quality
This is the best protection at the best image quality you can get!
Mesh made out of stainless steel to resist weather harsh conditions, and the suport ring out of rubber to absorb impacts on the mesh, secure grip fit and no scractching by taking in and out for lens cleaning.
