Fineshut KIWAMI is the upgraded version of our Fineshut SP that significantly improves its light absorption properties. This is achieved by forming numerous microscopic grooves
that absorb light emitted from the direction perpendicular to the grooves. It is made from the same polyurethane foam as our Fineshut SP. Particularly in the infrared range, it
has the second-best light-absorbing performance among our products. It achieves a total hemispherical absorption rate of 99% or more in a wide wavelength range of 250 to 2500 nm
with a thinness of only 0.37 mm!
